The install I ran the speedtest on is: FreeBSD baroque.ilse.net 4.10-STABLE FreeBSD 4.10-STABLE #23: Wed Aug 4 15= :18:52 CEST 2004 root@tango.ilse.net:/usr/obj/usr/src/sys/BAROQUE i386 and runs 6 nfsiods. How can I tell whether it uses transactions ? The NFS server is mounted with: mount_nfs -c -P -a 0 -r 8192 -w 8192 -i -o rw,noatime,nointr host:/path /nf= s/host/path Marc --/2994txjAzEdQwm5 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (FreeBSD) iD8DBQFCb9z7ezjnobFOgrERAmQOAJoDfa7AsatAKDhq0cwDrLbVT7DEPQCfXYns Sw74MaAy17ZweZ+q6DBOTkg= =Z8Mj -----END PGP SIGNATURE----- --/2994txjAzEdQwm5--
