if he has 2GB of RAM and the machine is not user by other means (is it?),
using 1GB for memory cache is not a bad idea, imho. Of course, he has to
check process memory limits etc.

in my experience the largest file that was fetched two times or more from
our cache, was ~20MB in its size and we have 30GB caches, and we use LFUDA
heap replacement policy. He uses lru replacement policy, where big objects
just decrease the cache efficiency.

Of course that highly depends on cache use, his clients/customers etc...
