Hi, On a network capable of scp-ing files between machines at 60MB/sec, we are only able to achieve 2-3MB/sec of throughput when using AFS. We've been conducting tests on 300MB files, by copying them from the /afs/* mount to the local filesystem with memcache enabled. In production, we will not be using memcache, but we wanted to eliminate the overhead of the on-disk cache manager. We've tried tweaking our options as follows: "-verbose -nosettime -memcache -chunksize 20 -stat 2800 -daemons 5 -volumes 128". The most important option is the chunksize, which did not have a measurable effect. Any other tips?
Thanks! Ken
