The load driver for these tests was an internally-developed Java application framework called
the Faban driver.
Conguration and Tuning
The following tuning settings are common to all the tests in this study. Individual studies may
also have additional conguration and tuning information.
/etc/system tuning:
set rlim_fd_max=500000
set rlim_fd_cur=500000
set sq_max_size=0
set consistent_coloring=2
set autoup=60
set ip:ip_squeue_bind=0
set ip:ip_soft_rings_cnt=0
set ip:ip_squeue_fanout=1
set ip:ip_squeue_enter=3
set ip:ip_squeue_worker_wait=0
set segmap_percent=6
set bufhwm=32768
