EEK time largely depends on the number of inodes in the filesystem.  For
example, if there is only one file in the filesystem, the size of the
filesystem does not matter much as far is eek is concerned.

=20

On an average, we can eek 100 million inodes in 10 hours (no quotas, no
snapshots, no other load on the filer etc).

Subject: Approximate eek time

=20

I see from the wiki that eek time is dependent upon a number of things
including size of filesystem, number of inodes, number of directories,
number of snapshots, etc.   I was wondering if I could give a client an
approximate time for an eek on a filesystem of a particular size.  The
client is trying to figure out how large they want their volumes to be.
Eek time might be a reason to keep the filesystem size to a reasonable
size.  The data they have are large files, no snapshots.  What are
approximate times for an eek to run on a 1Tb filesystem? On a 5Tb
filesystem?

=20

Thanks,
