FileChooserDialog is slow over nfs with many files....

[Jon Wright <wright esrf fr>]

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:
/usr/lib64/libgtk-x11-2.0.so.0.400.13

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:

$  strace -T -c ls /data/id11/inhouse/jon/old/grains/srcro4_layersiii |
