A distributed memory object caching system. There are five tests. These run on AMD system but appeared to hang on my Intel system. Overall a high level of interrupts.
Topdown profile shows a high level of frontend stalls and lower backend stalls.
AMD metrics show little floating point. There is a high opcache miss rate and relatively high icache miss rate.
