Subject [jira] [Commented] (HBASE-9959) Remove some array copy - server side
Date Wed, 13 Nov 2013 15:01:37 GMT

Nicolas Liochon commented on HBASE-9959:
----------------------------------------

bq. taking up BBs but maybe not a big win in this case?
It's difficult to say. Obviously, the region server is much more i/o bound than the client
so saving copies and allocation could be less interesting. I've fixed these one because they
were on the top list when I profiled the objects creation. I think it's useful at then end.
As well, with SSD &  so on we might expect the object creation to be more & more important,
so starting to use ByteBuffer likely a step in the right direction...
