Re: [Clonezilla-live] on-the-fly performance

[Steven S. <st...@nc...>]

Right now I do not have real machines which I can test. Therefore I can 
not give you the numbers.
If anyone on this forum has such numbers to share, please share that.

BTW, there is a performance improvement in partclone 0.2.8, and it's now 
included in clonezilla live 20100330-karmic. Could you please give it a 
try? To see if any big difference.
Please let us know the results if you try that.

Regards,
Steven.
