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

Looks like you did the recommended upgrade path, so that is good.

My next thought would be concurrent inserts since it is MyISAM. Try setting running "set global concurrent_insert = 2" and then testing insert speed.

On a side note, have you noticed any increase I/O since the upgrade?
