Both. Joshua> If you are using EBS, how many provisioned IOPS and how Joshua> many volumes are you using? In what configuration? It doesn't matter a iota what you use. It's the NFS4 server in FreeBSD. Not using any provisioned EBS. Have tested against ephemeral zfs mirror, ebs root disk ufs, and raidz2 zfs with 4 EBS disks. Joshua> What ec2 instance size are you using? m1.large. Joshua> Are you running your tests against the NFS server from Joshua> within EC2, or from a host outside of EC2? within same zone. All these details are irrelevant. See my test nfs3 versus nfs4. We have a factor 10 difference here. Any hardware/disk factor is irrelevant here. It's the FreeBSD nfs4 implementation. I wish I had the time to solve it, sounds like an interesting problem, but a lot of work I'm afraid. -- All the best, Berend de Boer ------------------------------------------------------ Awesome Drupal hosting: https://www.xplainhosting.com/ --pgp-sign-Multipart_Wed_Jul_31_18:37:27_2013-1 Content-Type: application/pgp-signature Content-Transfer-Encoding: 7bit Content-Description: OpenPGP Digital Signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (GNU/Linux) iQIcBAABCAAGBQJR+LCnAAoJEKOfeD48G3g5WzoQALOFFHdMcEzpZehWHGTaM5BI xaTaSFFI101WP8Z13rZEU4gffXXOyAHRWvpQACBhn5rF5BgiDxkLsRbNjhodBGVm 2yML8IJU+p3oNdTQDxMWRHfpYfvyBVNa1ifo3ki4xCzkgtE4ccb/HiGGE9C+JMKR IlfIeSpy0zBgFJnFO39bnCYgCWql+AveQ1TqunZevSZ+F18JEWHmoN5cmTAulJRm TcJ9yH4IzgUetS2KNh9PiLDp3mWnDA/IKtW3WXX43baeUb7AqvsPNf7iWhMpOiYd YQR7sNl2b1gXO+s4glRGDC4idTdqIs5S+Q6mOQESPVxgPNrLsQ19SYG6gNQ34Xz4 Xl0g/c0fxDiAA1skHseEP4Cuwo003msvEupxf/dgjY1+9jNq4lfQ/3sphalamPYc JdWYqLc77kyv8zkb4fn5nOSVBJCjrbq6eh5hLYoUYgY8j2Jwl5F9hH9H8aCdU/sM s2TqMWNWpPMjKrPq5mDAd+Ws7sVl2wTm4+bQJ207Pv6D42dCtNKpt78ovZeAhqG5 /rColvWPg4UuuAiz9qnwJTEfIn7Dg8oCLEISzXnZ1CnS+DoO8IJ4HUEqPQKvzDXz bIYZN6fpEftCUSSh9Nahy9WlgWOnw7d/rODwaok5G/cEgLCvEuZDoFjSYGWs8vtm fwLLXLi8Ypp0ASjaPuFo =7Lbs -----END PGP SIGNATURE----- --pgp-sign-Multipart_Wed_Jul_31_18:37:27_2013-1--
