Easy fix. Will do. The original version you had to tell it which kernel you were running so I can add that as optional. > I've found that tuning often helps response, like reducing memory with > older rmap versions (ran for a while using mem=256m), or tuning bdflush > with -aa kernels, which I did after Andrea gave me some serious hints. > Just a short string added to the version would make this a bit easier to > follow after the fact. Perfectly reasonable. Be aware though that reducing mem will also change the write size of io loads in contest. Although this will test the VM's response to half and full size writes it will also decrease the size of IO load. Con.
