Nginx + PHP-fpm + NFS poor performance

Hi.

I’m new with nginx and want to know if it is possible to implement this
architecture because we’re having a very poor performance over the same
tests against local installations.

For test we have 2 hosts. One with nginx+php-fpm+apc reading our php
code locally, and another one with the same server/software but reading
our php code from a NFS volume provided by a filer.

In the stress tests, the first one has a 12 requests/sec ratio but the
second one has only about 0,6 req/sec. The filer performance is OK since
we have a lot of apache servers serving our front pages from the same
volume without any problem, and the data collected by the filer tools
are OK.

So, what can be wrong? If need any piece of confs, please let me know.

Regards
