After flashing my sprint touch pro 2 it seems slower

[rigo]

Is it just me or is this true in every single case?? i used my touch pro 2 for about 2 weeks with out flashing a custom rom.. and it use to work super fast and smooth it almost never froze but now that i have tried about 4 custom roms and going back to the stock rom, my touch pro 2 seems to be slower and less responsive everything takes longer that before. is this normal? or is there something wrong with my pro 2?? i tried doing hard reset and try to run a very clean stock rom with no extra cabs but it still a little bit laggy
