Re: Which of these VPS configurations would perform better for Cassandra ?

[Radim Kolar]

workable configuration depends on your requirements. You need to develop 
own testing procedure.

How much data will have
whats 95 percentile response time target
size of rows
number of columns per row
data grow rate
data rewrite rate
ttl expiration used
never aim for "minimum". Cassandra has huge difference during load spikes.
