Hello,
Im reposting this topic from beta-forum, which seems to be closed.

Environment of version 11 is noticeably slower than previous version 10. It's hard to define all (slower) actions, I can describe one very simple operation. Steps are:
- start PLSQL Developer (without any connection)
- open 10 new "SQL windows"
- connect to (any) database (it makes all 10 windows connect to database)
- and now: just close all 10 windows as quickly as possible

I joined an attachment of screen captures - ver10 and ver11. This simple actiona takes me about 15sec in ver10, but 30sec in ver 11.

This is just example (I dont' enjoy closing ten windows every ten minutes) but there're a lot of actions slower than ver10 which is annoying, so I have to stay with 10 for now.

Thanks for response.
