Re: Postgresql Performance on an HP DL385 and

There is 64MB on the 6i and 192MB on the 642 controller. I wish the
controllers had a "wrieback" enable option like the LSI MegaRAID adapters
have. I have tried splitting the cache accelerator 25/75 75/25 0/100 100/0
but the results really did not improve.
