# DV4 tuned …

spent the weekend working on our DeltaV 4 unit, tuning it a bit. Previous write numbers were a bit lower than I liked.
So we adjusted some of the configuration a little. This is what resulted (old write numbers were in the 450MB/s region for this test)

Run status group 0 (all jobs):
WRITE: io=31,748MB, aggrb=788MB/s, minb=807MB/s, maxb=807MB/s, mint=40264msec, maxt=40264msec


This is way outside system cache. Its also faster than many of the hardware raid vendors machines in this size class, and far more cost effective.
