operating system - MySQL on PowerPC 64 -


i have web application uses mysql 5.6 db. application runs fast in x64 systems. have install application on powerpc 64 bit machine client. problem application runs fast on x64 , 7 times slow on rhel 6 in powerpc 64 bit machine. time difference due mysql performance in different machines. since mysql not provide binaries powerpcs, have compiled mysql source powerpcs.

  1. why mysql 5.6 running slow on powerpc 64 bit?
  2. will there improvement if aix os used instead of rhel?
  3. how can improve performance of mysql 5.6 in powerpc 64 bit?
  4. will there improvement if mysql 5.1 or lower version of mysql used?

thanks

you building source without explicit optimizations powerpc.

you may have better luck using optimizations tested here http://bugs.mysql.com/bug.php?id=39630 these done on mysql 5.1 should work fine 5.6 well. if not, downgrading mysql 5.1 have more tested optimizations powerpc
