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

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

Hi James,
Yes, we found there is an issue about partclone 0.2.7 performance. 
Therefore another Clonezilla live 20100330-karmic was uploaded with 
partclone 0.2.8 included. This issue should have been gone.
Could you please give it a try?
Please let us know the results.
Thanks.

Regards,
Steven.
