Hello, We recently conducted a test comparing the performance of Hypertable with that of HBase. The test is summarized in the following High Scalability post:
Hypertable Routs HBase in Performance Test -- HBase Overwhelmed by Garbage Collection<http://highscalability.com/blog/2012/2/7/hypertable-routs-hbase-in-performance-test-hbase-overwhelmed.html> We've also unveiled a new website, www.hypertable.com. If you haven't checked out Hypertable in a while, now would be a great time. - Doug
