Date Mon, 18 Nov 2013 17:31:21 GMT
Eric Newton created ACCUMULO-1905:
-------------------------------------

             Summary: WALog is slow
                 Key: ACCUMULO-1905
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-1905
             Project: Accumulo
          Issue Type: Bug
          Components: tserver
         Environment: hadoop 2.2.0, accumulo 1.6.0, hash 45fbee6937549048c74fe176f201c246de0f5e0a
            Reporter: Eric Newton
            Assignee: Eric Newton
            Priority: Critical
             Fix For: 1.6.0


I thought that the continuous ingest test was going slower than it used to.  I was getting
about 20K k-v/sec on my desktop.

After turning off the WALog, ingest shot up to 200K k-v/sec.  I expected some improvement,
but not an order of magnitude.
