Eric Newton commented on ACCUMULO-2388:
---------------------------------------
150K aggregate? That is significantly less than I would expect on that kind of
hardware.
What's the write rate you are seeing on minor compactions? The traces have
information about the size and times.
Are minor compactions backing up? What's the rate when the number of tablets
per server is ~80?
