[Gluster-devel] ls again

[Jordi Moles]

Hi everyone,

i was about to write a new message to this list to explain my new 
experiencies with "the ls problem".

This morning i updated both fuse and glusterfs to the latest tla 
versions, i used to have mainline2.5-patch 690, now i've got patch 736.

The thing is that i used to have "ls slow" commands when there was 
"some" activity in the filesystem.

But with today's update, the system is even slowler, with an empty 
filesystem, with no activity at all.... ls is really really slow.

is that normal?

these are extracts from my log files:

Nothing a part from the glusterfs version has changed... i mean... conf 
files are the same.... same machines.... and so on.....
