httperf warning

[Gardner Bell]

Hi,
I've been benchmarking Apache13 the past few days with httperf and
always see the following warning.  Open file limit > FD_SETSIZE;
limiting max. # of open files to FD_SETSIZE.  Can I safely increase
FD_SETSIZE without buggering anything up or is this something that
shouldn't be touched?  If it is safe to change is this an option that
one would compile into the kernel itself or is there another way of
doing so?
I'm thinking that it would be options FD_SETSIZE=2088, the 2088 being
equivalent kern.maxfiles?  I'm probbaly wrong with this assumption so
hopefully someone out there can help me out.

Thanks
Gardner
