Thomas,
Thanks for the help. I will talk to the file system team on what we can do.

The client on the server is running the 2.5.3 version. When I did an
initlal scan of another test system I saw scan rates of about 1000-2000
entries per second. While I had configured robinhood to monitor this new
system, the Robinhood server was not running when we started to copy data
to the new filesystem. From the changelog statistics, I am about 144m
events behind. Processing the change logs seems only be going at 375
entries per second.

events to be much faster than this or at least as fast as a normal file
scan.
