Hi Andrew,

just a very quick suggestion for now -- you could try disabling transport encryption and compression and see if you get better throughput.

And one question about the change: Have you touched the client on the Solaris host or the configuration (beyond changing credentials for the DIR)?

The reason I ask is that, as far as I recall, the openSSL and possibly compression libraries on Solaris may be just slow compared to other platforms.

'status client=<the-solaris-host-fd>' should give a bit of information about the client build in the header, and that may become interesting when we try to find out if the FD is potentially problematic.

Cheers,

Arno

Hello,

Have a strange one here. I have moved to a new Bacula Server and the read performance for a Solaris client is 3 times as bad.

All other clients (Windows, Linux) are good.

Old setup:

Solaris Bacula 13.04 Server (slow disks for spooling) LTO5 when backing up a Solaris file server I get:

     iostat gives me about 100Ms
     Bacula Backup report gives me ~ 54,664.4 KB/s

New Setup:

Ubuntu Bacula 13.04 Server (Fast disks for spooling) LTO9 when backup up save Solaris file server I get:

iostat gives me about 30Ms
Bacula Backup report gives me ~4,661.3 KB/s

But other clients Windows & linux are report good rates.

The conf files are near enough the same, so any ideas why Solaris is so slow when backup up to a Linux server?

Thanks,

Andrew
