I just downloaded, installed, start cassandra and ran very simple = "benchmark": write n times something with = key=3D=3Dvalue=3D=3DtestInsertAndGetAndRemove_n (one thread). For n=3D=3D10 million on a 7200rpm HDD (4G RAM - there should have be = "reasonably" free mem however I didn't check) this took 40min = (insert()ing one after another). Reading them one by one in sequence = delivers about 100/s, reading in 1.000er batches (i.e. multigetColumn()) = takes 5-10s (depending on n, the higher the slower). Are this typical numbers for cassandra (0.5)? I actually took the = configuration as it was.=20=
