XFS vs BTRFS performance with Qubes

I know that this is not xfs discussion but last question :rofl:

With xfs my avg boot up performance is under 30-35s without any vm started.
if you have free time, can you run systemd-analyze on dom0 without any auto start vm?

can you run systemd-analyze on dom0 without any auto start vm?

[user@dom0 ~]$ sudo systemd-analyze
Startup finished in 3.281s (kernel) + 5.351s (initrd) + 8.789s (userspace) = 17.422s

Lenovo ThinkPad T430
i7-3840QM
Samsung V-NAND SSD 860 PRO

time to start a qube = 10 sec

Without (firmware) and (loader) it just take me 13s to boot, and avg 6-8s for vm.
But I surprised even with old machine it almost beat :

  • I7-10750H
  • Seagate FireCuda 510

I’m interested in benchmarking btrfs next day and sorry for being oot.

Well, it depends how I measure.

[user@dom0 ~]$ date && qvm-start qube && date
Fri Oct 15 19:35:43 CDT 2021
Fri Oct 15 19:35:51 CDT 2021

→ 8 sec

[user@dom0 ~]$ date && qvm-run --pass-io qube "echo hello"  && date
Fri Oct 15 19:39:04 CDT 2021
hello
Fri Oct 15 19:39:14 CDT 2021

→ 10 sec

How do you measure? My point being: I believe I/O performance is of much higher importance than how many instructions per second your CPU can provide.

Now it kind of is (I split the threads). :wink:

Nope

Have try benchmarking today, using btrfs increase 2 second in dom0, and 1 sec in vm, haven’t try with large vm storage.
