Re: [qubes-users] Qubes 3.2-rc2 very high hard disk activity
Hi, Well, I restored qmmman.conf to defaults and it seems working fine now. I had a smaller cache-margin-factor which was probably causing hyperpagination on the AppVM's. I don't know why I didn't notice the same on 3.1. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

Take a look at `top` in dom0 and sort processes on memory usage (single '>' key press). If it's about some dom0 process using too much memory, you should see it there. Normally at the top should be Xorg process (on my system it has just under 200M in RES column, but you probably have even less). Also check swap usage in VMs - maybe its about some VM, not dom0? - -- Best Regards, Marek Marczykowski-Górecki Invisible Things Lab A: Because it messes up the order in which people normally read text.

[qubes-users] Qubes 3.2-rc2 very high hard disk activity
Hi The computer which I upgraded from 3.1 to 3.2 is having some performance problems when I have a few VMs running. It has a non-SSD hard disk so I know it's going to do a bottleneck and I don't expect a fast perform, but I'm sure that it's running very worse than it did with 3.1. Using iotop on dom0 I examined the process which use the hard disk when it goes totally lagged. I see: - Some [loopX] processess... are them loops for the VMs? I suppose it's normal to have a pretty high I/O work from this processes. - systemd-journald is pretty common when the lag starts, in fact I have 873Mb's on /var/log/journal , is this standard? - I also see some rsyslogd process and qvm-sync-clock I have to say that this never happened with Qubes 3.1, I just couldn't open more than 4/5 AppVM's, but it always worked pretty fine.
