Description Jiri Sedlacek 2011-10-29 09:47:02 UTC 
Profiling points implementation has several performance problems, which causes the code to be extremely slow in some cases (working with symlinks/network paths).

Some of the problems found so far:

 - saving dirty profiling points in EDT on IDE shutdown
 - ineffective resolving of project location in loops
 - ineffective resolving of profiling points storage in loops
 - ineffective algorithm of loading profiling points from storage
 - saving profiling points immediately after loading them
Comment 1 Jiri Sedlacek 2011-10-30 13:41:02 UTC 
Addressed the described problems. The affected code now runs ~10x faster.

Fixed by http://hg.netbeans.org/profiler-main/rev/e23c9f0ac3b1.
