Nicolas Liochon commented on HBASE-9775:
----------------------------------------

The results a few month ago were (taken from HBASE-6295)
||Test||Trunk||Nic||0.95||
|org,apache,hadoop,hbase,PerformanceEvaluation$RandomReadTest|1377.08|1420.14|1390.50|
|org,apache,hadoop,hbase,PerformanceEvaluation$RandomScanWithRange100Test|11243.12|10992.68|10971.09|
|org,apache,hadoop,hbase,PerformanceEvaluation$RandomSeekScanTest|304.66|296.43|305.25|
|org,apache,hadoop,hbase,PerformanceEvaluation$RandomWriteTest|9176.07|13619.59|9134.09|
|org,apache,hadoop,hbase,PerformanceEvaluation$SequentialWriteTest|13592.40|42655.52|13255.12|

The writes seems to be much faster on your new computer, while the reads are slower. But we
still have an improvement on 0.96 for the writes...
