Re: Why aptitude is sometimes slow inside xen domU ?

["Olivier B." <ob.nabble@daevel.fr>]

In fact in my case the domU is really really slow :
   time dd if=/dev/zero of=TEST bs=4k count=12500
   12500+0 enregistrements lus
   12500+0 enregistrements écrits
   51200000 bytes (51 MB) copied, 37,504 s, 1,4 MB/s

   real    0m37.520s
   user    0m0.004s
   sys    0m0.352s

1.4MB/s... and the Dom0 do only 40MB/s on write.

So it's not an aptitude problem.
Thanks,

Olivier
