Hello, We are in the process of evaluating Cassandra to be used with our product; I've started with some performance tests but unfortunately I'm getting very bad results for read operations (around 200 ms per read request which is much much more than what I'm reading that Cassandra can deliver).
- I'm using the latest stable Cassandra binaries (Cassandra 0.7) on Windows - My cluster has 3 nodes (on 3 separate machines), only one seed node and replication factor of 1 - I've use batch_mutate to insert around 50,000 keys with an average of 60 columns per key (no super-column) - I'm using C# client - The read operation I've tested was: for a random key get all its columns (using get_slice) I have 2 types of results: - as expected (very fast, around 1 ms per read request) when the client is running on one of the 3 machines and is connected with the local machine - under expectation (200 ms per request) when the client is running on one of the 3 machines but is connected to one of the other 2 machines (except local machine). It might be configuration issue but I cannot figure it out. Any suggestion? Thank you, George
