Yes, another test system (P5 MMX/233 laptop) drops its NFS throughput
from 4MB/sec to 2.5MB/sec when built with those flags. So I'm assuming
you're doing these benchmarks on a comparable system?
I think this just demonstrates that you should not run benchmarks with
all your debugging flags enabled :) Most people will not be running
production systems with WITNESS, and parts of the kernel that bog down
under the heavy load of WITNESS may work just fine on a regular kernal
config.
