For those of you out there using Samba to re-export a Lustre filesystem, is there any particular tuning that needs to occur for optimal performance? I ask because at least so far, in my current tests, metadata operations seem pretty slow, e.g. 15% - 50% of what I''m getting using a local IDE disk (Lustre is running over 100Mb/s ethernet). Throughput is as I anticipated. I have adjusted lru_size a bit, and that seems to help; just wondering if I''m missing anything else. Cheers, Ken Smith
