If in the kernprof data you find "fget" as one of the high rankers (say in top
10) then can you try the scalable FD management patch which uses
read-copy-update mechanism for protecting files_struct.
As of now there are working patches available for read-copy-update mechanism
and FD management at "http://lse.sourceforge.net/locking/rclock.html" as
rclock-2.4.2-01.patch and files_struct_rcu-2.4.2-03.patch but we are working on
simpler interfaces. Also let me know if you need the patches for a different
2.4 kernel version.
