We have power problem and in order to keep mysql data in tact I disabled write cache. But it turned out to be a disaster as php application speed was affected. The disk is not behaving even after enabling the cache.

comment escaping in crontab
In my case it works only if there is no space. for e.g. "test1\|pqr". But you are correct, there is no need of escaping in this case.

comment define software path
Point 2 and 3 worked. The software was not installed using rpm so rpm -e is not working to remove the old version.

comment RAID 0 for better MySQL performance
Maybe I have not explained my question correctly. I need to know only the performance difference between RAID-0 and not using RAID at-all.
