When does Tomcat add and remove threads from its internal thread pool? I'm
talking about the threads with names like http-nio-8080-exec-1. It appears the
thread pool is Tomcat's own ThreadPoolExecutor but I don't see the exact
behavior documented. I'm familiar with

Folks,
I've been using Tomcat for a long time but am new-ish to NIO (Tomcat 8.5.) It
seems that one of the big benefits of NIO is decoupling the worker threads from
the client connections. I can now have a large number of open connections
without a corresponding large number of threads.

Hi all,
I'm interested in knowing how many new incoming connections are being created,
possibly per connector. Does Tomcat have such a thing? I assume it would
involve counting calls to ServerSocketChannel.accept() or something like that.

All,
I'm using Tomcat 7.0.82 and java 1.8.0_152.

the same machine using the same JDK. It accepts EC ciphers just fine so I

The short question is that my client is sometimes not getting the 0-length

I cannot get my connection or thread count over 100 no matter how much load I
throw at the server. Currently I just have a dummy app deployed that doesn't
do much except sleep for about 500ms and return a canned response. Initially I

I'm doing some scalability testing of an app in Tomcat 7.0.73.
Some relevant connector config details:
maxThreads=80
maxKeepAliveRequests=100
keepAliveTimeout=1
maxConnections unspecified (defaults to maxThreads according to the docs)

Sorry for top posting. The format got weird.
Those numbers aren’t bad. The most important number for me is the throughput
on the summary tab. Yours is 99.38%. That means the JVM was doing real work
99.38% of the time and garbage collecting the other .62%. You could improve
that if you
Enable verbose SSL.
Start Tomcat with -Djavax.net.debug=ssl. That will print a lot of info to
catalina.out.
You could also do the same thing on the client side if you used a java client,
or something similar with OpenSSL, curl, etc.

I'm using Tomcat 7.0.70 and am having trouble understanding why Tomcat is

almost no load on the server, I get "Connection: close" pretty much every time.
The client is sending "Connection: keep-alive" but it
