Stefan Seelmann commented on DIRSTUDIO-1119:
--------------------------------------------
I tested on Linux. Opening a group with 1000 members works well. Also a group
with 10k members works but it takes approx. 10 seconds to open the entry. But
what I see is that memory usage increases, from 50MB to 230MB but after running
GC most is free again, even if the 10k members entry is still shown. So I
assume we do some very inefficient things when loading the entry into the
editor, a quick look with JVisualVM proves that.
Can you check the memory consumption when opening groups with many members? In
Preferences->General please enable "Show heap status", then in the status bar
you shouls see the memory usage. You can also try to increase the memory
(https://directory.apache.org/studio/faqs.html#how-to-increase-the-heap-memory).
