Marco, I've figured it out, copy paste gets slower with the amount of windows open in the application. Any idea why? My laptop has more than enough memory available to handle it.
I went back to version 14. The only reason is the slower UI of the 15 Not only the copy/paste, but the whole UI seems to be less responsive for me. Somehow I feel, that my PC is struggling to draw the user interface. But it is not true, because I have an Intel i5-10400, with 6 cores, 12 threads, and 16GB of memory.
I've installed 64bit I've disabled copy history I've disabled copy font Performance on v15 is still sluggish I've disabled the same settings on v14 (32bit) and it still runs way better than v15
Is this related to other programs running at the same time? In the past this happened for me, but only when running PL/SQL D after first opening Excel (or something like that).
If we can give Marco a testcase he can reproduce then this will definitely get fixed.
The feedback from Allround could be improved. Is the performance problem described comprehensible or reproducible? Is it being worked on or is there no solution? I waste time every day with this annoying 1-2 seconds with every copy.
PL/SQL Developer has been having performance issues when many files / windows (in PL/SQL Developer) are opened. Memory used by PL/SQL Developer doesn't grow when opening more windows (according to task manager) which I wouldn't mind one bit as I have plenty of that.
BTW, I cant reproduce copy performance issues even with 20 files opened. One of the things I don't use is the Ribbon or Lint. (Never liked it, I have a wide screen monitor and it uses valuable vertical space. Also I can never find anything on the ribbon.). Don't think I have other settings that could improve this set...
I went back to version 14. The only reason is the slower UI of the 15 frown Not only the copy/paste, but the whole UI seems to be less responsive for me.
I think I'm seeing same/similar issue. I generate CLOBs with XML data. Opened a result in Large Data Editor window. There is a little bit lag in opening the window, but then I can see the data, the size (about 4,5 MB in this case). One can see it is all loaded in the window. Can scroll down to the end of the text.
I select all and hit Ctrl-C. App freezes. It has now been running one core at 100% for 20+ minutes. I recently updated from 14, and while I noticed a significant delay there also, it was nowhere as close.
The problem with the very slow copy/paste behaviour also persists in dark mode. In the standard mode (light and dark = <none>) the copy/past performance is much better (as in previous versions). Is there anything that can be improved?
Hi all - here is another suggestion where I feel I had some improvement in the app's performance:
1. Make a note of all your preference settings that you've modified. 2. Close PL/SQL-D (make sure you're running 64bit) 3. Move all of the "old" preferences to a backup location: your username directory shouldn't be in the Preference folder anymore: C:\Users\<Your Username>\AppData\Roaming\PLSQL Developer 15\Preferences\<Your Username> 4. Start up PL/SQL-D (it should now start up with the default system preferences) 5. Manually add in your old Preferences or leave it default.
Also remember to do the following: Disable Clipboard History Disable Include font style with copy Under "Object Browser" - ensure that the "Default user selection" is set to CURRENT USER
Another suggestion I see from the previous post, is not to use dark mode - I haven't tried this, but with the above I'm currently running dark mode.
