If you don't mind about I/O scheduling latencies then just use elvtune and
set read/write latency to a big number (for example 1000000) and set the
write-bomb logic value to 128. However in misc usage you care about
responsiveness as well as latency so you probably don't want to disable
the I/O scheduler completly. The write bomb logic defaul value is too
strict probably and we may want to enlarge it to 32 or 64 to allow SCSI
to be more effective.
About the bad VM performance of the latest kernels please try again with
pre9-1 + classzone-28.
