[PhillyOnRails] Garbage collection

Toby mentioned garbage collection and memory usage. While most of us aren't doing T's, even in normal rails use, GC has an impact.

While seemingly a "low-level" detail, garbage collection can make a huge (33%-100%) difference in requests per second.

Also, Toby:

I don't know if you read eigenclass.org -- HIGHLY RECCOMENDED -- but there was a recent post about memory use with small objects that may interest you: http://eigenclass.org/hiki.rb?ruby+space+overhead
