Re: [Bacula-users] Slow backup on Sparc SunFire 280R

[Gabriele Bulfon]

When the sparc machine are just clients, I may achieve 2-4Mb/sec
When these machines are both servers and clients (backup themselves), often I achieve less then 1Mb!!

Just to exclude network!

What is the transfer rate that you can achieve with those servers?
