Hello! > In my experience upping it can increase NFS performance a lot. Indeed, 256K is too low. Even TCP needs ~512K window on gige. Actually, gentle hint to Bob was to estimate minimal threshold, when evicton completely stops on myrinet. This can be taken as new default, adjusted to lower values for low memory configurations.
