Mikhail Antonov commented on HBASE-11219:
-----------------------------------------
I meant method-local, of course - sorry. I think reducing number of allocations
is good (yet I don't know how big win it is here, as seems these buffers
should be collected in young gen anyway?)
> HRegionServer#createRegionLoad() should reuse RegionLoad.Builder instance
> when called in a loop

> As Andrew showed in the attachment to HBASE-11165,
> ClusterStatusProtos$RegionLoad$Builder took 25MB heap space.
> buildServerLoad() calls createRegionLoad() for each region on the region
> server.
> One instance of ClusterStatusProtos$RegionLoad$Builder can be created outside
> the loop and passed to createRegionLoad().
> Thanks Andrew for the finding.
