> It takes a long time (more than 10 minutes) to load 10k queues in SLS. The
> problem should be in {{com.codahale.metrics.CsvReporter}} based on the result
> from profiler. SLS creates 14 .csv files for each leaf queue, and update them
> constantly during execution. It is not necessary to log information for
> inactive queues.
