What is the best thing I can do in order to increase NFS performance on our central file server? Facts: ----- * Sun 3/280 * SunOs 4.1 * 8 Mb memory * 5 Gb disk (6 disks on 2 xd753) * Serves approx 100 clients with USER files (the clients have their root and swap on other servers) * Low write percentage (about 3%) (write + create + remove) * CPU idle time > 50% * Load average approx 5. Possible solutions: ------------------ 1. Upgrade to sun4 (4/380?) * Does this help when the cpu is idle most of the time? 2. Add more memory * Gives me more diskcache. * Is there any way to list some stats for the cache? vmstat showes about 250 K free list size, but does this include the disk cache, or can the free list borrow pages from the disk cache if it needs more? 3. Buy a Prestoserve * Is this really usefull when the write percentage is low? Please email, I'll summarize. Per Foreby; perf@efd.lth.se; LTH-E, Box 118, S-221 00 LUND, Sweden; 046-107492
