Hi!
I was trying F840 on Solaris 8. Transfer rate with large files was great, but on smal files (2k) was not so good. I used default NFS mount options. Should I do some NFS optimization? Is there a white paper on it?
Best regards, Uros _____________________________

Small files are always slower than large files, mainly because you have more files for the same amount of data and you transport more smaller data blocks.
Your goal therefore has to be to minimize latency (Gigabit ethernet, fast disk drives) and to maximize caching (NFS v3, some Sol8 kernel tunings).
Filers also handle concurrent loads very well. If you can parallelize your application into multiple threads (and you haven't done so yet), it will become faster. But again, Sol8 kernel tunings might become necessary, especially on multiprocessor machines.
