Question on insert performance

[Michael Dagaev <mi...@gmail.com>]

Hi, all

       We are running tests inserting data into Hbase and noticed
that some inserts (~10%) take very long time to complete (> 2 sec).
Sometimes one insert may take even > 10 sec.

Has anybody come across a similar problem?

Thank you for your cooperation,
M.

What else is happening at the time of the insert Michael?  Is the region 
being inserted into in the midst of a split?  If so, client must ride 
across the close on regionserver and reopen on a new.  This can often 
take seconds and even tens of seconds for sure.
