Bill Farner commented on AURORA-1481:
-------------------------------------

Any chance you could reproduce this in the vagrant environment?  If we can repro it easily,
it would be a nice proof of a fix.

> The Thermos Observer when default configured with 5 second polling interval takes up
to 150% cpu on an aws c3.4xlarge. This is with
> ~10k executors
> ~1 run per executor
> Haven't done any profiling, but the overall design seems to be inefficient given it has
to list read the entire directory tree every time and do a fair amount of regex parsing.
