User Comments:
c69: I tried to Open File from "my documents", there is 1600 files, most them are images.
Dialog hanged for some time, but eventually closed (because i was clicking the X button during the time it was lagging).

MackSix: Open File in directory with a lot of files.

Maximum slowness yet reported was 51168 ms, average is 48945

The slowness was caused by JFileChooser. It seems that the hard drive was quite slow, probably under heavy load.
This cannot be fixed in NetBeans.
Thank you for reporting.

Problem in preforming File operations in EDT.
Please extend NetBeans file chooser to avoid File operations in EDT.
Comment 4 Jaroslav Havlin 2015-09-03 13:20:45 UTC
Adding 8.1_WAIVER_REQUEST keyword.

The slowness is mostly reported from Windows OS, whose NTFS filesystem is sometimes too slow. The fix could be quite complicated and risky, so I would like to waive this issue for now.

Thank you for understanding.

Bug waiver for 8.1 approved.
