Hello
I am having troubles with PL/SQL Developer on DB with many packages and data. Oracle SQL Developer works just fine.
I have tried all guidelines on this forum.
Thanks

Can you let me know exactly when performance is poor? What kind of actions are you performing that are slow?

Opening packages, just scrolling down the packages, data fetching

Executing statement

To obtain some more diagnostic information, can you modify the shortcut and add the DebugSQL parameter? For example:

"C:\Program Files\PLSQL Developer 12\plsqldev.exe" DebugSQL

Reproduce the problem and send me the debug.txt file that is generated in the %APPDATA%\PLSQL Developer 12 directory (e.g. C:\Users\<User>\AppData\Roaming\PLSQL Developer 12).

Hi

Was there any feedback regarding this? I'm seeing the same performance issues?

Regards,
Kenny

Agreed - opening packages takes about 5 seconds compared to v11 opening in less than a second. Switching databases is slow. It's faster to close everything and open pl/sql developer again.

I stand with the decreasing (in negative sense) performance of plsql developer (coming from version 5.x).

Thought was the (distributed) environment
When writing some simple applications with lazarus and oracle components things truely fly. Even with xmltype/blobs, which really, really hurt in plsql developer when co-selected in queries.

Think performance and snappyness should be highest on the list for new version(s).

I agree with above members, performance of PL/SQL Developer has been degrading over the years and it would be on of my most favoured improvements if the developer could improve this.

That said, some things I did that improved responsiveness of PL/SQL Developer:
1) disabled the clipboard history. (preferences - editor - clipboard)
2) made sure nls_sort from backend and client matched(registry - Oracle home)

If we're sharing performance-increasing tips, mine is:
Turn off Preferences->Connection->Store recent history

My problems related to slow startup and connection-switching went away when I turned that setting off.
