Home -> Community -> Mailing Lists -> Oracle-L -> RE: PERFORMANCE question?
By any chance you have your redo logs on RAID05. Looking the wait timings I strongly feel your I/O sub system is over loaded. Pls let us know the hardware architecture. (Disk config, raid, etc). That would help us understanding your problem better.

log file sync value is increasing and waits are high.when i check all ratios
the ratios looks good.What could be problem?
