mounted file system bottleneck

mounted file system bottleneck

[Jason Czerak]

I believe I found some sort of bottleneck with mounted networked file
systems over 10Gig Ethernet.  I've posted a question to linux-net with
zero response since Friday.

http://www.uwsg.indiana.edu/hypermail/linux/net/0809.3/0013.html

Could a few of you folks here take a look at this and tell me what you
think is the issue?

You're posting a support question to a developer list.  This is frowned upon. 
You might get more attention here if you conduct a more scientific test and 
report it in a more scientific fashion.

This is also frowned upon.  Please send your data directly to the list, unless 
it is absolutely enormous.

Offhand, I'd guess atime updates.  Unless you're seeing this on a new upstream 
kernel, you should contact your vendor for support.  Or NetApp.
