    [ https://issues.apache.org/jira/browse/HBASE-1185?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12678750#action_12678750

Billy Pearson commented on HBASE-1185:

no big deal just thought it should report correctly sense we where under reporting the speeds.

>                 Key: HBASE-1185
>                 URL: https://issues.apache.org/jira/browse/HBASE-1185
>             Project: Hadoop HBase
>          Issue Type: Bug
>          Components: client, regionserver
>    Affects Versions: 0.19.0
>         Environment: 0.19.0
>            Reporter: Billy Pearson
>            Priority: Minor
>             Fix For: 0.20.0
> I am seeing lower number of request in the masters gui then I have seen in 0.18.0 while
> I thank part of it is we moved to report per sec request not per 3 secs so the request
should be 1/3 of the old numbers I was getting.
> hbase.client.scanner.caching is not the reason the request are under reported.
> I set hbase.client.scanner.caching = 1 and still get about 2K request a sec in the gui
> but when the job is done I take records / job time and get 36,324/ records /sec. So
> there must be some caching out side of the hbase.client.scanner.caching making the
> request per sec lower then it should be. I know it running faster then reported just
> it might give some new users the wrong impression that request/sec = read/write /sec.
