[Bacula-users] backups with SSL over WAN very slow

Hi.

I've got a very weird thing going on here.

First the components:
   - FD on Windows Server 2008, it's 64-bit, first it was version 5.0.3 
and upgrading it to 5.2.10 did not make any difference. FD is configured 
to use both SSL and encryption.
   - SD 1 on FreeBSD-9.0 with ZFS, 32-bit 5.2.12. It's a remote storage 
and connection from FD is over WAN.
   - SD 2 on FreeBSD-9.0 with ZFS, 64-bit 5.2.12. It's a local storage 
and connection from FD is over LAN (different VLAN).

Backups from the Windows FD started running very slow (150-200 KB/s) at 
some point. Other backups from the same environment to the same remote 
SD run as fast as the remote WAN-connection allows.

I tested these combinations and got such results:
   - SSL + encryption + local SD -- fast
   - SSL + local SD -- fast
   - encryption + local SD -- fast
   - encryption + remote SD -- fast
   - SSL + remote SD -- slow
   - SSL + encryption + remote SD -- slow

It seems that whenever I set FD to use SSL over WAN, the backups start 
running low.

Has anyone else experienced something like that?
Any guesses where to look for the problem?
