Hello, I'm experiencing slow write speeds on 8-STABLE running on an ESXI 4.0 server, despite whatever tunables I've thrown at it. Read speeds are slower than they should be, but acceptable. Note, this is a thick provisioned disk, not thin.
Speeds on Windows hosts are as expected for an MD3000 DAS, 250MB/s or so.
