Re: Cassandra and LINUX CPU Context Switches

This would be normal if the switches are user to kernel mode (disk & network IO are kernel mode activities). If your run queue (jobs waiting to run) is much larger than the number of cores (just a swag but less than 2-3*# of cores), you might have other issues. *...* *Daemeon C.M. Reiydell

Cassandra and LINUX CPU Context Switches

I've noticed that my apache-cassandra 2.2.6 process is consistently performing CPU Context Switches above 10,000 per second. Is this to be expected or should I be looking into ways to lower the number of context switches done on my Cassandra cluster? Thanks in advance. [Ericsson]
