this script in particular:

<Hotkey F1>
<Toggle>
<SendLabel w2, w3>
<Key S>
<wait 500>
<Key 1>

i understand that there is a wait 500 tag, the delay that i mention, is in addition to the 500 ms that has been introduced to the hotkey.

also, i have set the affinity for my wow clients:

wow1 to cpu 0,1,6,7
wow2 to cpu 2,3
wow3 to cpu 4,5
