Description ehucka 2006-08-08 09:54:37 UTC 
Profiler dev 060808, jdk 1.6.0

It seems heapwalker or its ui has performance problems which affect rest of ide.

Example: I have a heapdump of tomcat server (cca 14MB) I selected 'char[]' class
and its instances. Than I selected an instance - CPU went to 100% for a few
seconds than the Fields list showed <Searching...> for another seconds. After
the Fields table had showen new content CPU worked in 100% for about 5-10 seconds.

So selecting of one instance takes about 20 seconds and during this time ide is
unresponsible. Another thing is after each repaint of ide the opened heapwalker
takes about 2-3 seconds of 100% cpu.
Comment 1 Jiri Sedlacek 2006-08-08 10:15:30 UTC 
Partially fixed by fixing Issue 82051, the rest will be fixed by collapsing 
treetable data by 500 nodes as described in the same issue.

Lowering priority as heapwalker shouldn't block IDE any more.
Comment 2 Jiri Sedlacek 2006-10-16 15:55:24 UTC 
Collapsing of array items and list of instances implemented in trunk (will be 
in M4).
