Thanks Quanah. I'll test different number of threads, beginning with 8, and post the result in this list.
About DB_CONFIG file, I didn't create... I'll rtfm and create one. :) However, are there some parameters or values that can increase the performance and maybe solve the problem?
Having DB_CONFIG is one of them. Also see "cachesize" and "idlcachesize".
