Description nbphpuser 2010-11-18 11:31:23 UTC 
While editing big files CPU usage about 30-50% (see attachments). Not only CC is slow, writing simple comment line or whatever causes CPU load about 20-30%. Of course, one shouldn't create such big files.

I have looked through the snapshot and it seems that the bulk of time was spent in the refreshing index. I will look at this more closely.
Comment 4 Petr Pisl 2010-12-06 14:59:03 UTC 
I have committed some improvements today for editing bigger files. It should be available in tomorrows build. Could you check it then? Thanks.
Comment 5 Petr Pisl 2010-12-06 16:32:29 UTC 
I'm cloing now this issue. Please reopen, if you think that it's not better. I have play with your example file and CPU usage was better during writing.
Comment 6 nbphpuser 2010-12-06 17:05:47 UTC 
it is definitely better now! Thanks!
