Well, there's one way to find out for sure... Simon covered server tweaking in general, but for throughput on a server that's not particularly loaded, my first guess might be -rxpck specifically. I recall some people have reported significant throughput improvement when it's raised to even 2000 or higher. To see if it's the client or the server that's the bottleneck, you could try a throughput test with afsio or afscp. If that yields a much faster result, you're likely hitting bottlenecks in the cache manager code. It could also be slower, though, if you've tweaked afsd's rx settings, as I don't think afsio or afscp allow you to tune those. (afsio is in src/venus, afscp is src/tests) -- Andrew Deason [email protected] _______________________________________________ OpenAFS-info mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-info
