1. $ticks - %t is not a milliseconds value.
2. That wouldn't really help pinpoints slowdowns in a large blackbox as Deathwolf is describing.
@Deathwolf: Unfortunately, there's no way to tell what part of a script is slowing you down besides manually testing each event independently of others. I'd unload scripts until the slowdown is gone then focus on the last file you unloaded... assuming you have scripts loaded.
Also look at loaded dlls by typing //echo -a $dll(0) to see if you have any loaded and then $dll(1) $dll(2) ... to the number returned by $dll(0) to see each file. You can unload them with //dll -u $dll(N)
