As long as you stay within the ram usage limitations (see the Suqid FAQ
for ram vs cache sizing) the size of your cache has marginal impact on
performance, except that hit ratio increases somewhat with larger
caches.
As for cache sizing: Having a cache much bigger than 1 weeks of traffic
is not very cost effective. The cache hitratio benefits of making the
cache larger is marginal and significantly lower than the cost increases
for the server.. (mainly RAM cost, unless you hit 2GB in memory
requirements forcing you to select a 64 bit CPU architecture further
increasing the costs and memory usage..)
