So this finally has come to light after a number of people internally tried to highlight that DPS (BURA, BRS, DPAD, DPS, we keep changing our names every year to throw them off the scent) software is in need of starting over. Data Domain is still a single controller limited by CPU and also Garbage collection hinders the performance with Avamar workloads. It is a mess over here, but we just keep smiling and pushing our products.
