> I'm looking at startup time on a cluster with lots of data per node. On this
> cluster, the tablet server takes about 30 seconds to start the
> LogBlockManager, and appears CPU bound. I grabbed a profile and it seems like
> most of the CPU is spent in MemTracker::Release and Consume (see attached
> flame graph).
