Yes, of course, I really meant that the way OpenAFS client provides encryption is really "spectacularly bad", as you wrote! Giovanni On 13/10/20 21:33, Benjamin Kaduk wrote: On Tue, Oct 13, 2020 at 09:26:43PM +0200, Giovanni Bracco wrote: Sorry for the typing mistake in previous mail, but yo

Sorry for the typing mistake in previous mail, but you got the point! Now with the proper setting at the client startup the result is clear, the low performance was indeed due to encryption on! Thank you, the case is solved but it is indeed impressive that encrypting the data transfer reduce

Hi Giovanni, What you write is generally correct or close to correct, but some details differ and I don't know if they are artifacts of your email or reflect your actual testing. `fs setcrypt -crypt on` and `fs setcrypt -crypt off` are indeed the ways to configure the (non-)use of encryption for

Thank you for the suggestion, but I have tried to use the command fs setcrypt -crypt off on 1.8.x clients and fs setcrypt -crypt on 1.6.x clients without any effect on performance in both cases, no increase for 1.8.x and no decrease for 1.6.x Is that the way to control the encryption, is

I have seen that the first release of OpenAFS 1.9.0 is out and so I thought that it was time to try at least 1.8.x and also 1.9 on our production Linux x86-64 nodes, where we have used 1.6.x up to now. Our AFS cell has file servers with OpenAFS 1.6.x and while over WAN the performance can be r
