Cassandra is heavily multithreaded. If the load demands it will make use of your 8 cores.

I dont know the startup code, but I would assume it would be parallelized if neccessary/possible. Afaik there were optimizations already made to reduce the startup time. Therefore I would assume any optimizations left would not be so easy.

Hello All,
We are thinking of going with Cassandra on a 8 core machine, are there any optimizations that can help us here ?

I have seen that during startup stage Cassandra uses only one core, is there a way we can speed up the startup process ?

Thanks !
