Hi Lars, thanks for your reply.

Thanks for mentioning this and that's exactly what I'm wondering about. Encryption too is involved when doing SCP transfers (even stronger encryption, such as Blowfish or AES 256) and I get scp speeds of 60 to 82 MB/sec when transferring to native ext3 fs. So, my question is: Why is there almost no decrease when using SCP with a strong encryption algorithm (compared to plain DES that AFS uses) but there is *drastic* decrease in performance with only plain DES enabled compared to an unencrypted transfer? > E.g. my workstation client (linux) does 10-12 MB/sec with encryption > enabled, but >70 MB/sec with encryption disabled. > My point is on: disable encryption. > Btw, our linux clients does roughly 20-50 MB/sec so far.
