[OpenAFS] 1.4.0 fileserver performance question

[Joe Buehler]

Using oprofile on a RedHat 9 SMP machine with dual 2.4 GHz
xeon processors, I see the following instruction counts
on the machine:

000024e0 8543     1.1778      ip_packet_match
/lib/modules/2.4.20-35.9smp/kernel/net/ipv4/netfilter/ip_tables.o
08099d50 9641     1.32918     bn_mul_add_words
/var/cfengine/bin/cfservd
4207a6c0 10193    1.40528     strncpy                 /lib/tls/libc-2.3.2.so
00000000 18407    2.53772     (no symbol)             /usr/sbin/mysqld
c026d32c 19006    2.6203      csum_partial_copy_generic
/boot/vmlinux-2.4.20-35.9smp
08064560 117205   16.1587     BreakDelayedCallBacks_r
/usr/afs/bin/fileserver

I.e., oprofile is saying that the machine is running 16% of its
instructions in the BreakDelayedCallBacks_r routine in the fileserver.

Is this anomalous?
