DO NOT REPLY [Bug 51145] New: Need a NIO-based AJP connector
https://issues.apache.org/bugzilla/show_bug.cgi?id=51145 Bug #: 51145 Summary: Need a NIO-based AJP connector Product: Tomcat 7 Version: unspecified Platform: All OS/Version: All Status: NEW Severity: enhancement Priority: P2 Component: Connectors AssignedTo: dev@tomcat.apache.org ReportedBy: je...@ptc.com Classification: Unclassified One of the major changes in Tomcat 7 is that it supports the Servlet 3.0 specification. A major part of the Servlet 3.0 specification is obviously the support for asynchronous requests. Some of us need to use Apache and mod_jk to provide load balancing over multiple Tomcats. This means using the AJP connector, which currently has only BIO and APR options. For those of us needing to support many (7) different platforms (some with horrific linkers, etc), APR is just not a workable solution -- too many nasty builds. For such use cases a NIO-based AJP connector would really be enormously helpful. Mark Thomas stated, I don't know how much work that would be to write but with the refactoring already completed for Tomcat 7 it might be as little as 1000 lines of code. -- Configure bugmail: https://issues.apache.org/bugzilla/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. - To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org

For keep alive situations, reduce maxConnections to something closer to maxThreads (the default config is 10,000 keepalive connections serviced by 200 threads with a 60 second keepalive timeout, which could lead to some large backlogs of connected sockets that take 50 minutes to get serviced) This is still an issue. I'm still thinking about how to address it. My current thinking is: - BIO: Introduce simulated polling using a short timeout (see below) - NIO: Leave as is - APR: Make maxConnections and pollerSize synonyms - All: Make the default for maxConnections 8192 so it is consistent with the current APR default. The other option is dropping maxConnections entirely from the NIO and APR connectors. That would align the code with the docs. The only downside is that the NIO connector would no longer have an option to limit the connections. I'm not sure that is much of an issue since I don't recall any demands for such a limit from the user community. Apologies for what I expect will turn out to be a long e-mail. I have reached the point where I believe the best way forward is: - remove maxConnections from NIO and APR - remove the ability to set maxConnections for BIO and hard code it to maxThreads - restore the disable keep-alive when 75% BIO threads are in use My reasoning is as follows: - Servlet 3.0 async requests mean that current connections in use may be greater then current threads in use. - This provides potential efficiency savings as less threads are required. - That connections may be greater than threads led to the new maxConnections attribute. - maxConnections maxThreads introduces an issue where a connection with data may be in the connection queue waiting for a thread whilst all the threads are busy doing nothing waiting for data on connections that will eventually time out. - This issue can be fixed with simulated polling. - Testing showed that simulated polling was very CPU intensive (I saw a typical increase from ~40% to ~50% CPU usage with 4 Tomcat threads, 2 'fast' client threads making requests as fast as they could, 10 'slow' client threads making a request every 5s and a pollTime of 100ms on an 8-core machine. - The additional resources required by simulated polling are likely to be greater than those saved by reduced thread usage. - It is therefore better to just increase maxThreads, expecting that not all of them will be used and hard-code maxConnections to the same number as maxThreads. Better still, just use NIO. Further, the complexity of BIO code required to support: - Optional configuration of maxConnections maxThreads - simulated polling when maxConnections maxThreads - auto-disabling of keep-alive for users that don't want the overhead of simulated polling when maxConnections == maxThreads was getting to the point where I had stability concerns. Given the above, and assuming there are no objections, I intend to implement the way forward I set out above tomorrow.

For keep alive situations, reduce maxConnections to something closer to maxThreads (the default config is 10,000 keepalive connections serviced by 200 threads with a 60 second keepalive timeout, which could lead to some large backlogs of connected sockets that take 50 minutes to get serviced) This is still an issue. I'm still thinking about how to address it. My current thinking is: - BIO: Introduce simulated polling using a short timeout (see below) - NIO: Leave as is - APR: Make maxConnections and pollerSize synonyms - All: Make the default for maxConnections 8192 so it is consistent with the current APR default. The other option is dropping maxConnections entirely from the NIO and APR connectors. That would align the code with the docs. The only downside is that the NIO connector would no longer have an option to limit the connections. I'm not sure that is much of an issue since I don't recall any demands for such a limit from the user community. Apologies for what I expect will turn out to be a long e-mail. I have reached the point where I believe the best way forward is: - remove maxConnections from NIO and APR - remove the ability to set maxConnections for BIO and hard code it to maxThreads -1 maxConnections serves a purpose. It protects against a DoS. There must be a way to configure a system to eventually push back, and not just keep accepting connections. Therefor the maxConnections should stay. - restore the disable keep-alive when75% BIO threads are in use why, make it configurable. I would believe that on many systems, the queued approach that BIO has, still can provide significant improvement in performance. If I don't want queued behavior, I'll just turn off keep alive. My reasoning is as follows: - Servlet 3.0 async requests mean that current connections in use may be greater then current threads in use. - This provides potential efficiency savings as less threads are required. - That connections may be greater than threads led to the new maxConnections attribute. the maxConnections attribute is simply to restrict the acceptor thread from just going on and on. It had nothing to do with servlet 3 or async. It's a protective measure for the server. - maxConnections maxThreads introduces an issue where a connection with data may be in the connection queue waiting for a thread whilst all the threads are busy doing nothing waiting for data on connections that will eventually time out. and this is still better than simply not accepting any connections at all. Right now, in order to work around the blocking aspect, one has to configure acceptCount so that connections are not simply turned away. - This issue can be fixed with simulated polling. I wouldn't do simulated polling. I'm not sure what benefit there would be. - Testing showed that simulated polling was very CPU intensive (I saw a typical increase from ~40% to ~50% CPU usage with 4 Tomcat threads, 2 'fast' client threads making requests as fast as they could, 10 'slow' client threads making a request every 5s and a pollTime of 100ms on an 8-core machine. - The additional resources required by simulated polling are likely to be greater than those saved by reduced thread usage. - It is therefore better to just increase maxThreads, expecting that not all of them will be used and hard-code maxConnections to the same number as maxThreads. Better still, just use NIO. you still need maxConnection Further, the complexity of BIO code required to support: - Optional configuration of maxConnections maxThreads - simulated polling when maxConnections maxThreads - auto-disabling of keep-alive for users that don't want the overhead of simulated polling when maxConnections == maxThreads was getting to the point where I had stability concerns. Given the above, and assuming there are no objections, I intend to implement the way forward I set out above tomorrow. I'm confused about what you are trying to do or achieve.

BIO performance issues
All, Summary --- While trying to align the documentation for maxConnections with the actual implementation a couple of performance issue have been identified with the BIO connector. All bar one of these have been fixed. A fix needs to be agreed for the remaining issue, ideally before the next 7.0.x release. Background -- New connections to the BIO connector are placed in a queue. When a thread is available, it takes the next connection of the queue and processes it. When the connection has been processed if the connection is kept-alive it is placed back on the queue. If there is no keep-alive the connection is closed. Scenario This ended up being very long, so I moved it to the end. The exact pattern of delays will vary depending on timeouts, request frequency etc. but the scenario shows an example of how delays can occur. The short version is that requests with data to process (particularly new connections) tend to get delayed in the queue waiting for a thread to process them when the threads are all tied up processing keep-alive connections. Root cause -- The underlying cause of all of the performance issues observed is when the threads are tied up doing HTTP keep-alive when there is no data process but there are other connections in the queue that do have data that could be processed. Solution A -- NIO is designed to handle this using a poller. That isn't available to BIO so I attempted to simulate it. That generated excessive CPU load so I do not think simulated polling is the tight solution. Solution B -- Return to the Tomcat 6 implementation where maxConnections == maxThreads. Additional clean-up --- maxConnections is unnecessary in APR since pollerSize performs the same function. Summary --- The proposed changes are: a) restore disabling keep-alive when threads used = 75% of maxThreads b) remove maxConnections and associated code from the APR connector c) remove the configuration options for maxConnections from the BIO connector d) use maxThreads instead of maxConnections for the BIO connector e) update the docs Mark Scenario BIO connector, default configuration - maxThreads=200 - maxConnections=1 - keepAliveTimeout=connectionTimeout=2 (20s) When there are less than maxThreads current connections, no issues are observed. Consider the following scenario: - Start from zero load. - Clients make 1 request every 5 seconds and use HTTP keep-alive - Clients ramp up from 0 to 1000 at the rate of 100 new clients every second. I'll call each block of 100 clients group A, B, C, ..., J. - Assume request processing takes 0s just to keep the numbers simple. I've tried several ways to express this. This is verbose, but hopefully clear. There may be some mistakes in the detail but the overall result is consistent with observations of some JMeter test runs.
