I have a form with 7 quicktables(in different tabs) and it's noticeably slower than JTables when closing.
This form takes much longer to close than other forms in my application.
Is there any way I can improve this? There is a lot of information I need to display and
would much rather use quicktables. Also, there is no problem with only one quicktable on a form.

when you close the form, what exactly are you doing? I assume that you are using JFrame, Are you disposing the frame when users close the frame?

I am disposing of the frame.

Could you add some timing statements and tell me which method is taking long time. For example, on close if you are just calling dispose. Just put some timing statement around it and tell me how long it takes to execute.

I measured the time in milliseconds around dispose and got these results:
quicktable w/ data:
1016 miliseconds.
1094 miliseconds.
985 miliseconds.
937 miliseconds.
quicktable no data:
1000 miliseconds.
891 miliseconds.
844 miliseconds.
jtable no data:
15 miliseconds.
16 miliseconds.
32 miliseconds.

Even with 2 tables on a form, it is slow to dispose. We are able to hide the other forms.
So, they don't have this problem. Has anyone else had this issue?

I tried compiling an older source and it is not slow disposing.
Another developer made some small changes to the source though.
I am trying to find out if those changes are causing this or if it was
introduced in a newer version.

We had some memory issues related to dates which have been adressed in the latest version. Are you using many date columns in your quicktables?
Anyway, we will send you the latest version, please contact us at support at quicktable .org

It seems to be a change from the march to may version. Compiling the original source from May has this problem. The other developer who is handing quicktable will be getting the latest version and I will try that.

The new source has the same problem. We are temporarily using March's source.
Wehave not figured out what the problem is.

I believe the problem is being caused by cleanup in DBTable.
System.gc is called at each dispose through this function.
IMHO, calling the garbage collector directly usually does not help since it is called
automatically when needed. This alone speeds it up considerably.
Two other changes seem appropriate as well. Setting parentFrame = null seems
unneccessary since the object is being disposed anyway. Similarly, findFrame.removeAll() and
tempFrame.removeAll() seem unneccessary since those frames are being
disposed. These changes make disposing virtually instanteous.

Thanks for reporting the problem.
We had some memory leak issues while using quicktable with JInternalFrame. JInternalFrame doesn't release the memory after it is closed.
Some of those fixes might not be necessary, we will do some more cleanup of the code and do a release.
