>
> While investigating a pretty severe performance regression comparing YCSB
> against 1.6 and 1.7, I found a fair bit of lock contention around getting
> configuration values. This was improved by ACCUMULO-4388, but various threads
> eventually all started contending on the configuration values expected from
> the site xml files.
