You can adapt some of the benchmark programs from http://shootout.alioth.debian.org/ I can not see it being used for much except trying a new language or a benchmark.

The compilation performance reminds me of the 'beloved' time sharing systems of the eighties and earlier. Had to go to work in the middle of the night, so compilations didn't take an unpredictably long time. With PC's (CP/M-80, XENIX) came more predictable performance. Feels like a history repeat - going back to the terminal age with HTML forms somewhat like 3270 submit and AJAX more like DEC VT-100. Not exactly of course, but like a pendulum swinging from server-side to client-side and now back to server-side.

It's not sad. As a new service, people are going to check to see if it works at all before spending time doing something more complex.
