We recently ran a few tests on mysql on both solaris and linux environments. It turned out that mysql was much faster and responsive on linux. After doing some digging, we found out one of the possible reasons is the fact that mysql source code uses malloc all over the place.
On solaris malloc calls block all threads and create heap contention. Indeed, Sun actually dis-courages the use of malloc. This would explain why we could never see our CPU utilization go up on solaris.
Question #1) are we right in our assumption that mysql runs way faster on linux rather then solaris or are we on drugs.
Question #2) If it does indeed run faster, is there a way or a ported binary of mysql that runs equally fast on Solaris. Reason being I have two big Sun E3500 lying around that I would like to put to good use ..
Thanks in advance,
Aamir
