Hey does anybody know technologies that vimeo uses? I understand they will use mysql for that db, unsure when they use memcache.
The website appears pretty smooth in comparison to youtube.
From header assessments It certainly uses php. Probably it will use memcache. The recording content appears to become straming from the specialized server I'm not sure of (bit_asic/3.3/r2f1-bitcast-a ). Some reactions originate from Apache Covalent which aludes to java. Located on debian etch.
Because of the choice between asking us (who've most likely never labored at vimeo) and vimeo itself (who'd understand what technologies they will use), I'd go for vimeo (email@example.com).

You might like to try asking on Hacker News. They have a tendency to understand much more about infrastructure issues.
