AFAICT the main advantage of APR wrt static content is the possibility to use sendfile. In my experience usage of sendfile increases throughput significantly - at least with big files and provided that the speed of the network connection, disk IO etc. is not a limiting factor. The one drawback I see wrt sendfile is that the size of the content transmitted via sendfile won't add to the internal counters, i. e. the size of the file transferred will show up neither in the access log (if enabled) nor in the Bytes sent information the manager app displays on the Server Status page. Of course, depending on one's needs this may be an issue or not.

HI, I'm wondering something. My tomcat serves static content without APR. is there a big performance increase serving static pages with APR enabled ? Thanks in advance.

I am just wandering about when to use the APR and when not to, especially for those of us using Apache as a front end (although in my case this is done solely to integrate perl and java apps into a common namespace) Gregor Schneider wrote: Take a look at the Apache Portable Runtime: It will increase Tomcat's performance regarding static content sigificantly: http://tomcat.apache.org/tomcat-6.0-doc/apr.html Cheers Gregor - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: tomcat in production
Abdul, There is no specific version of Tomcat for production * as long as * you stick to the last revision of your branch, since it contains all security bug fixes for that branch. There are no patches in Tomcat, only further releases. Moreover, it is advised that you use the Tomcat 6.0 branch, or at least the 5.5 branch, if you can. For instance, for the 6.0 branch, the last revision is 6.0.14. Which branch you will choose (6.0, 5.5, 4.1, etc) depends upon which version of the servlet and JSP specifications you use. Regarding the tips to apply, someone had once posted a great blog entry on this list, which we have long discussed : http://www.digitalsanctum.com/2007/08/18/20-tips-for-using-tomcat-in-production/ HTH, Pierre 2007/11/12, abdul razack [EMAIL PROTECTED]: Hi, we have web application running in iplanet server. we want same web application running on Tomcat in production. Is there any separate tomcat version for Production. If so, please give me the link to dowanload. Is it ok if I download any version of tomcat from http://tomcat.apache.org/. what are basic configuration that I need to do for running tomcat in production.
