The cassandra stress tool gives me values around 2.5 milli seconds for writing. The problem with the Cassandra Stress Tool is that it just gives the average latency numbers and the average latency numbers that i am getting are comparable in some cases. It is the 95 percentile and 99 percentile numbers are the ones that are bad. So it means that the 95% of requests are really bad and the rest 5% are really good that makes the average go down.
No, the opposite is true. 95% of the requests are fast, and 5% is slow. Or in case of the 99 percentile, 99% is fast, 1% is slow. Except if you order your samples in the opposite direction, not in the usual.
