Jean-Marc Spaggiari commented on HBASE-10089:
---------------------------------------------
I have some free time this WE to test it if you want. But I don't think we will
see much differences.
One option is to script a loop to create/drop tables in the 2 version and
compare, and for perf, maybe something doing random tables gets with existing
and non-existing names and compare?

> As part of the metrics system introduced in HBASE-4768 there are two places
> that hbase uses String interning ( SchemaConfigured and SchemaMetrics ).
> This includes interning table names. We have long running environment where
> we run regular integration tests on our application using hbase. Those tests
> create and drop tables with new names regularly. These leads to filling up
> the permgen with interned table names. Workaround is to periodically restart
> the region servers.
