If you're using Resin Pro on the target of those conditional GET requests, and your app knows how to invalidate the cache only when the response data is changed, you can see some real benefit. If there has been no change, Resin Pro will respond with a 304 - Not Modified. In other words, the majority of request/ response cycles would be comprised only of HTTP headers with no message body. The open-source version, without some intermediary like Squid running in server-accelerator mode, can only respond to the request by executing whatever process is involved to generate the response, and sends HTTP responses which always include the message body. By using Resin Pro to cache the output from your process, you gain two advantages over Squid: First, the response is cached as an output stream, not written as a file. Second, Resin Pro's cache is threaded, Squid is not. For the app we're developing using a REST approach, Resin Pro should perform better in testing, since without it the application would not scale well under load as it's basically a recursive HTTP request using chained filters. The tradeoff is a larger RAM requirement, which I'll take if it saves a lot of HD reading and writing or CPU cycles. -Eric ___ resin-interest mailing list resin-interest@caucho.com http://maillist.caucho.com/mailman/listinfo/resin-interest
Re: [Resin-interest] resin speed
Yes, we are currently using Apache 2.0.46, which is the current version provided with Red Hat Enterprise 3. My plan is to eventually remove Apache from the mix once I have replaced the dependencies on it. I expect overall performance to increase since Resin will be handling the requests directly without them being transferred over a port to Apache. I can't comment if there is a performance difference between the open source version and professional version. If there is a difference, I doubt you would see it in testing. Maybe someone else can comment on this.

Hi Markus, Thank you very much for the comments.. earlier I didn't know about JProfiler.. I'll look into it.. Thanks again.

Re: [Resin-interest] resin speed
Hi Akila, I can also tell from our experience, like Keith's, that Resin has a very fast response time. We use Apache 2.x as the frontend, combined with Resin-Pro 3.0.21 & Sun JDK 1.5 & Redhat Enterprise. During peak times, we have a load of about 40-50 page requests per second, and Resin handles this load. When the traffic is not that high, even through WAN, the pages are served in less than 1 sec. The same is true for Resin without mod_caucho - we can tell that because our servers are accessible with and without Apache the whole time. If hardware does not seem to be the problem (enought RAM, new etc.), chances are very high that it's your app, so what I would advice you is to get a profiler like JProfiler and monitor your app. You will definitely find clues to your performance problems that way.

Re: [Resin-interest] resin speed
Hi Keith, Are you running Resin with apache ? cos I hooked up with apache and did some fine tuning in it... and now it seems serve up pages bit fast. Anyway I use open source version and i think there might be more features on professional one.

Re: [Resin-interest] resin speed
Akila, We have been using Resin for the past five years to serve up the Go2marine boat parts store ( http://www.go2marine.com ), and we have always found it to have a very fast page response time. We are currently running Resin Professional 3.0.19 in production. We are using Sun's 1.5.0_09 JDK. The OS is Red Hat Enterprise 3 ES. The database is Oracle 9i, which runs on a separate server. When we refactored the software to use Struts and Tiles last spring, I was concerned that it might impact performance because of all of the internal HTTP requests for the tiles. No worries. I was delighted with how fast the site ran. The times that we have run into problems with page response time is when the server becomes heavily loaded in production. These problems were corrected by tuning memory, increasing threads, or increasing the maximum sessions. Keith Akila Amarathunga wrote: > Hi All, > > I'm quiet new to Resin...
