Ted Yu commented on HBASE-3701:
-------------------------------
I think these two lines in HConnectionManager.processBatchCallback() can use
presize:
{code}
List<Row> actions = new ArrayList<Row>();
List<HServerAddress> addresses = new ArrayList<HServerAddress>();
{code}
> revisit ArrayList creation

> I am attaching the file which lists the files where ArrayList() is called
> without specifying initial size.
> We should identify which calls should use pre-sizing to boost performance.
