[Bacula-users] Anyway to do multi-core compression?
Are there any pending plans to add a multi core option to the FD to enable compression to happen on more than one core? We have a few eight-core servers that are rather idle during the backup window, so it would be great to use more than one core for compression. Something like a Max Core direction for the FD would be cool! :) j -- Joshua Kugler Part-Time System Admin/Programmer http://www.eeinternet.com PGP Key: http://pgp.mit.edu/ ID 0xDB26D7CE -- This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword ___ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users

Oh, I'm sure it could detect the number of cores, that wasn't my issue. I was more concerned with making sure that the little bit of traffic we would get during the backup window wouldn't timeout because it's using all eight cores. I'd probably use six of the eight cores for compression. j -- Joshua Kugler Part-Time System Admin/Programmer http://www.eeinternet.com PGP Key: http://pgp.mit.edu/ ID 0xDB26D7CE -- This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword ___ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
