Massive increase in CPU use since "upgrading" to 2.2.11

Since the upgrade, my server’s CPU is effectively pinned whenever a backup is running, has some new “feature” been added, and if so how do I disable it to get back to sane resource usage?

If previous versions had been like this I’d have abandoned UrBackup on day 1 and looked for something less resource intensive…

Vm I’m running on is Windows 2012 R2 assigned 4GB of ram and 1 CPU which was plenty when it ran CrashPlan Host is a Dual Xeon blade, 2 CPUs 4 cores each.
