Subject [jira] [Resolved] (INFRA-11416) backup performance testing
Date Wed, 16 Mar 2016 01:12:33 GMT

Chris Lambertus resolved INFRA-11416.
    Resolution: Fixed

Migrating from zmanda on an AWS instance to a VM in the Illiad (France) data center caused
a reduction in backup performance down to around 2-3Mbit, which was not sufficient to sustain
larger backups of things like svn.

Working with online.net support staff and doing a variety of IO and bandwidth testing, we
determined that there were no inherent network or machine-level problems which would explain
the 3Mbit performance .

After opening a case with Zmanda and trying a number of test scenarios, I ultimately switched
the backup from the bsdtcp (xinetd) transport to an ssh-based transport, which has completely
resolved the performance issue.

from AWS to bai has been plagued with performance problems.
