Lets leave aside database and IO for a second. Lets assume my apps dont use
them. If I have an object with about 1000 Decimal variables. As per the docs
this will consume 16,000 bytes of memory or roughly 15K. Now if my server
had 1GB RAM, that would give me a max possible of about 69,000 objects
living in memory. Ofcourse that is assuming all memory is reserved for my
objects which is not the case. OS, Services etc need RAM. I guess I could
add more RAM if the server could take it.

thanks!
