When a netsplit happens in a channel with like 2000 people in it, and a majority of those people are split, then it really lags my mIRC (as in takes like 15 seconds to do one action (not pingwise)), and lags my Computer quite a bit, until the split is finished. I think it could be a number of things. I have logging turned on. Having to log 1000+ lines in an instant could be whats lagging me. Or maybe mIRC just doesn't handle splits all that well. I can't test it without logging because I need to have it on at all times. Does anyone else have this problem? If so, do you know of a way to fix it (other than turning off logging)?

mIRC 6.14 (no script(packs) like noname script or invision or anything like that, only small scripts i've made myself)
