Created attachment 163087 [details] selfSampler A few of the files I am editing take a significant hit when editing. It appears to happen only when adding or deleting lines in a file, and when doing so, the ide freezes for 2 to 7 seconds. This particular file is 5200 lines of I followed this description (http://wiki.netbeans.org/FaqProfileMeNow) and captured three snapshots. Unfortunately, this web page might be out of date, because it did not open any of the snapshots. There were other slowness events during this time reported as http://statistics.netbeans.org/analytics/detail.do?id=227374 However, those were marked as debugger slowness. The attached selfsampler files are just for one added line of code.
