[Box Backup] Performance with Box Backup Server

[Torsten]

Hi,

we have about 15 box backup clients connected to an dual core opteron with 
1800 MHz. The box backup server runs inside an xen domU with 256 megabytes 
ram assigned (Debian Etch).

There is a heavy overload (permanently between 2 and 4) in the xen domain and 
also on the xen server dom0. This overload is not directly produced by box 
backup but by massive I/O activities.

I have found this patch for box backup and it sounds good for me:

http://boxbackup.org/trac/ticket/45

Does anybody use this patch? Are there any problems with this?

Any other ideas?

Thank you
  Torsten
