No, Ive just installed new version, without param change.

But there is one thing - I had plsqldeveloper opened all night and today switching was slower then yesterday. Not as bad as in 11.0.0 was, but slower then in 10. After closing plsqdeveloper and reopen it switching speed is quick again. And problem wasnt just only in switch between windows, but on switching in sql window between sql and outpout too.
I try to test it tomorrow, Ill let plsqldeveloper opened all night and then let inform you if this problem appears again.

It's fast again after restart.
It seems to slow down faster and more tremendously too, when more PL-SQL-Developer-instances with lots of window-list-items are open.

So Ive done test again as I promise. Ill let it open whole night and today it was slow again. Click to next window takes around 3 seconds. After close and open again plsqldeveloper it goes back to normal speed. Hope this info helps with problem resolution.

Can you try this preliminary version and let me know if this affects the issue?

I'd like to test performance in new version too but my trial period for 11 expired so I'm screwed

You can send an e-mail to support@allroundautomations.com to obtain a trial extension.

Ill try it today, so results you will have yesterday. Anyway I had plsqldeveloper open from Saturday, today response looks fine, till I clicked on connections. Unroll connection list from "hidden" window is slow and it looks like after that click between window list starts to be slow too. After close and reopen plsqldevelper connection window and window list is quick again. Not sure if there are any dependencies between connection and window list, but maybe this will help you to find why this happens.

Another test - when Ill connect to my production DB, open one sql window with select, second window with connect to production DB switch between sql and output is fast. When Ill connect on second window to my test DB switching between sql and output become slow. Not so much but its visible. Closing window with testDB will not help. Ill try another test
open one livedb window, second livedb window. Do select on first window, switch between sql and output, speed was Ok - almost invisible speed.
Close second window, response of switching sql-outpout in first window starts to become slower. Its under 1s, but its visible.
Ill open second window, now Ill connect to testDB and switching between sql-output become more visible, it takes maybe 1s now..

Open connection window will take more than 1s (maybe 2s?).

On new version youve send me its almost the same, maybe open connection window is little quicker after last test.

I dont understand what dependencies are there, hope that
youll find them.

Hi Marco
New version looks fine, it looks like its no slower then yesterday when it run all night, Ill try to let it go today night and we will see yesterday if it will be the same. But for first sight its quicker then old 11 version, which is today slower as we expected.
The problem with slower response (click to new window, switch between sql and output) when open window to test DB persist.

After few tests - new test version have the same problem as old one, after opening few new windows with new connections it become slower and slower. Im unable to work with it, because wait 3 seconds to switch between windows is really annoying. From my point of view this is bigger problem than that plsqldeveloper become little slower when run whole night. I may restart it on morning, but when it become slower everytime Ill open new window, this is something I cannot use for daily work.

I can confirm Pavels problems. My first post about success after installing 11.0.1 was to early.
And no improvement with 1101.1765 ...
