slow cast attack

Hello

i use innerspace with ISB tools since only few days and i have a little problem with speed of casting.
Before i use AHK and i see that all keys and casting key attack feel like ... slow sleepy.
it s like to think less than 1 sec before each cast.
Where can i search to have a fast key answer ?

i try with 4 cors on the 5 wow.
i try with 2 cors on each wow and same.
i use jamba and focus target with assist ISB.
i use the wizard to start
no other add on

My rig specific
i7 920 / 12Go RAM / CG MSI 285 OC 1Go ram / data file on adaptec2405 raid0 4 ssd / OS W7 x64 on velociraptor / G19 keyboard / mouse G5
One screen 24in for 5 wow
main wow full maxi except shadow and weather, 1600X1024 1 DK
each slave all mini except range see detection, 1024X768 4 chamy

You should be using 8 cores, set affinity to 255. otherwise it sounds more like lag then your system.

lag ?
you think it s lag ?
with AHK, its fast but when i load/use innerspace, each key ask few times more.

i think 4 true cores are better than 8 half falss cores, no ?
Wow was build for 2 cores so blizzard change now ?

Are you using X-Fire? There is a known issue with using X-Fire with Inner Space that causes some performance problems.

Otherwise I'm not really sure what you're saying. I would try closing other running programs, though.

X-Fire for chat ?
no, i stop all programs except the anti virus

ok, when i hit one key, i need to wait maybe 0.5 second or 1 second to see the result. So all the game is slower
