Description Tomas Zezula 2008-10-15 11:00:09 UTC
The JavaTypeProvider creates lots of useless slow FileObjects which causes significant delay when Go To Type is used for first time after IDE start.
Comment 1 Tomas Zezula 2008-10-15 11:06:19 UTC
Info from David's log files:

Go to type for the first time took 10s after IDE start and in other invocations less than 3s.
1) The filesystem is cold, so the first access to the lucene indexes takes longer time (2-3s), we can't probably do anything
with this.
2) Even more time is spent in the call of ClassPath.getRoots(), something about 6s, I will rewrite it to use URLs.
