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..)
