Quoting Dan Lukes <dan@obluda.cz> (from Thu, 12 Oct 2006 09:43:20 +0200): [moved from security@ to performance@] > =09The main problem is - 6.x is still not competitive replacement for > 4.x. I'm NOT speaking about old unsupported hardware - I speaked about > performance in some situation and believe in it's stability. You can't be sure that a committer has the resources to setup an =20 environment where he is able to reproduce your performance problems. =20 You on the other hand have hands-on experience with the performance =20 problem. If you are able to setup a -current system (because there are =20 changes which may affect performance already, and it is the place =20 where the nuw stuff will be developt) which exposes the bad behavior, =20 you could make yourself familiar with the pmc framework =20 (http://wiki.freebsd.org/PmcTools, I'm sure jkoshy@ will help if you =20 have questions) and point out the bottlenecks on current@ and/or =20 performance@ (something similar happened for MySQL, and now we have a =20 webpage in the wiki about it). Without such reports, we can't handle =20 the issue. Further discussion about this should happen in performance@ or current@... Bye, Alexander. --=20 "A penny for your thoughts?"
