Re: major lost of performance after moving Bacula Server from Solaris to linux for Solaris clients only

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
