Note that Unix FS will slow down as disks get full. One may be able to
start filling at 120/sec but may have to decrease the rate to 50req/sec
when the disks are close to full. That is one of the reasons to keep cache
disks only 50% utilized...
Try this: Right after the experiment died at 120/sec. Clear the cache (or
re-point cache_dir to an empty disk) and quickly restart the experiment. If
you get back to 120/sec, it may be the file system playing its dirty tricks
on you...

P.S. I assume you've checked "netstat -m" and "netstat -p tcp" for network
related warning signs... :)
