Are you talking about 70MB/s despooling speed or 70 MB/s full job
speed. If its the latter that is probably all you can do because
bacula does not simultaneously spool and despool a single job at the
same time. If you use concurrency and more than 1 job you can get
better utilization of the tape drive.
As for 32/64 bit os. Its been at minimum 5 years since I have
installed a linux box with a 32 bit os. 64 bit has been stable for
quite some time. Although I have only installed in this time opensuse,
ubuntu, and gentoo. I but I do manage dozens of linux boxes..
