-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 All,
I was recently discussing garbage collectors with a friend (yes, an exciting conversation) and I was wondering what the folks in the Tomcat community were using for their garbage collection needs. I'd like to run an informal poll. Feel free to reply to just me directly if you'd like to protect your reputation or not clog the list or to the whole list if you'd prefer. I know there are lots of lurkers on the list who rarely post and I'd encourage them to reply as well even if they don't feel like they are running anything of any importance. So, here are my questions: 1. What JVM are you using? [ ] Sun/Oracle/OpenJDK Java 1.5 [ ] IBM Java 1.5 [ ] Sun/Oracle/OpenJDK Java 1.6 [ ] IBM Java 1.6 [ ] Sun/Oracle/OpenJDK Java 1.7 [ ] IBM Java 1.7 [ ] Sun/Oracle/OpenJDK Java 1.8 [ ] Something else - please specify: 2. What kind of web application are you running? [ ] A toy, a research project, or something with virtually no use [ ] A moderately busy web site (<1M requests/mo/server) [ ] A moderately busy web site (<10M requests/mo/server) [ ] A busy web site (10M - 100M requests/mo/server) [ ] A super-busy web site 3. What is your total heap size? 4. Are you explicitly specifying a Garbage Collector? If not, just say so and skip the rest of the questions. 5. What led you to use [GC X] instead of the JVM's default collector? 6. Did you do any actual performance testing to see if the switch from the default to [GC X] made any difference? 6. Have you spent a lot of time tuning [GC X]? 7. Did your tuning exercise yield any useful results? 8. Did your users notice any difference after you implemented [GC X], or just your own load-testing team? If you think there's anything else I should know about your experience with [GC X], please let me know. Thanks, - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.15 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBCAAGBQJSsiu1AAoJEBzwKT+lPKRYdAsQAKWytJHCv3Kj8p8vWoDsCgEO LZd6Yq/j8j5uID+UM4pq8FgRN03TmmjujOZaQ769ljZqtd9w+VFf2+zPbt7gPqGI SDFACw+VtQxEmVUDhE4H0tBfz7h7SZ8QOPTyScx384mDAvRzJKaeGPwrbJBogvaW cvyzNtgFDywpNTCjyKT3JLoUfjm+CjLryK6bo3+6I7I3ikhyHVsYZHuls5DG9LNf mYJ2KGOeYN332VcJWaCElLiK2HQrFY+BxfJ+f7mH6ztmq0iawulg8bApUo+vllwD r2Ble1kc0pgwMn4jOoRAP1R9IaFSsPX8a87T1uFtnRS0vdW4BRy6O5xE1wjFQPuq 52jcFf7i5ZiFYIXO1/vWw9FjZ2DBXnjMuEEdPf5laHNXKJIMCnulKOC6W48eS6Rq E7hRa7h+RQ0CVk9Pjp2NGdiPAeRL44LRDWaPWmTH7iXUcaWg2IxC3OXXyezP6aPE 7DrKhW9jjxbQG/H3GXzX9Sptee+osfPUaU6sOND8EYUYLojg6b6XLxfbjLpedrsh eHC1zksbc0WkZxhnXDSPZV4+4y0djC0X+tNX/DPCs/wPpXEqmqeGSXc7sbnXoLYf 49jGRa6pz8MR1da5D78lSCxm407+UNJzbJuGfHFzjYqxjQEULKJTug4Z7Hs0MGne XzAqLyKxfgW0/4P5QzD6 =EFcD -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
