milleruntime opened a new pull request #669: Use optimized writeV methods in 
Mutations
URL: https://github.com/apache/accumulo/pull/669
 
 
   * Moved optimized writeVLong and writeVInt to UnsynchronizedBuffer
   to replace use of WriteableUtils methods. Each optimized method will
   only make one write call to the underlying outputstream.
   
   This was mainly done as an attempt to improve WAL performance. It "should" 
help performance of mutations overall since the Hadoop WriteableUtils method 
can make multiple write calls per long.
