> In some highly concurrent benchmarks (100 threads or so), the persistent cache is sometimes
blocked, mainly in the (in-memory) cache. This should be resolved. One problem seems to be
fixed in a newer version of the MVStore (the "file system cache"), and the other cache bottleneck
should be solved using a config option for the segmentCount.
