Hello,
Opening a gtk FileChooserDialog is painfully slow for me on some nfs
directories containing many files. strace shows a lot of time calling
"stat". About 5 times for each of the files in the directory.
Is there a way to switch off the calls to 'stat' and just show a list of
filenames without modification time details etc?
Thanks for any advice, technical details are below,
Jon

FileChooser is coming from:

Test script opens a FileChooserDialog - it takes 10 seconds to appear
$ strace -T -c test.py

ls gives the filenames in the directory almost instantly:
