Re: 5.1 to 5.5 upgrade causes significant write slowdown (MyISAM + indexes)

Both OS are the same now (Fedora Core 17). The only difference should be hardware at this point. I think default filesystem is ext4.

As far as both RAID cards, perhaps both are not the best cards, but the main question remains as to why the old setup performs writes significantly faster and without high I/O/load...

I am wondering if the Dell R210ii is not on par with the R200..
