jacktang··on 6 Line EventMachine Bugfix = 2x faster GC, 13x requests/sec
Well, one of my friends drop me one formula. Let x to be the rate of GC time out of total running time, and we can get

(1-2x) * 14 = 1- x => x = 13/27

which means now ruby spends 13/27 time on GC, fast enough? (before patch, it spends 26/27 time on GC, really bad)

jacktang··on Ask YC: do you still on the way
Yeah, cperciva, I read the "Summer 2009 Funding" post and raise the question.

YC, I am a bit confused with the sentences:

"$5000 + $5000n is not a lot, but it turns out to be enough. It will cover at least 4 months' living expenses, and that is enough time to build something nontrivial."

After 4 months, what milestone should the team arrives so that you judge the project is promising? should I prove the business model is correct in the 4 months?
