* Add metrics for psutil derived memory usageErik Johnston2016-07-201-0/+38
|
* Change CacheMetrics to be quickerErik Johnston2016-06-031-22/+22
| | | | | | We change it so that each cache has an individual CacheMetric, instead of having one global CacheMetric. This means that when a cache tries to increment a counter it does not need to go through so many indirections.
