Converting bytes to hex string is unnecessarily slow
----------------------------------------------------
Key: CASSANDRA-2850
URL: https://issues.apache.org/jira/browse/CASSANDRA-2850
Project: Cassandra
Issue Type: Improvement
Components: Core
Affects Versions: 0.8.1
Reporter: David Allsopp
Priority: Minor
Fix For: 0.8.2
ByteBufferUtil.bytesToHex() is unnecessarily slow - it doesn't pre-size the
StringBuilder (so several re-sizes will be needed behind the scenes) and it
makes quite a few method calls per byte.
(OK, this may be a premature optimisation, but I couldn't resist, and it's a
small change)
Will attach patch shortly that speeds it up by about x3, plus benchmarking test.
