I'm using following script with "iozone -a" ($Revision: 3.24 $): -- VER=3 # 2 or 3 PRO=udp # tcp or udp mount -o nosuid,rw,vers=${VER},proto=${PRO},intr,soft freebsd:/export /mnt ( cd /mnt ; iozone -a ) > iozone.${VER}.${PRO}.output umount /mnt -- Combinations 2/TCP, 2/UDP and 3/TCP run fine, but 3/UDP repeatedly reports "RPC: Timed out" (always in last section, where column KB is 524288), for example: # ./run.sh NFS setattr failed for server kunhuta: error 5 (RPC: Timed out) fdopen: Connection timed out Please, is it reproducible on the other sites? Or is it a natural behavior because of UDP protocol use? -- Rudolf Cejka (cejkar@dcse.fee.vutbr.cz; http://www.fee.vutbr.cz/~cejkar) Brno University of Technology, Faculty of El.
