Memcached and Fotolog
Memcached has been working great for Fotolog for quite some time now. Today I found a quote by our CTO on memcached site.
"I have a new memcached user to add to your list: we here at Fotolog, the world's largest photo blogging community, now use it and we love it. I just rolled our first code to use it into production today and it has been a lifesaver. I can't wait to start using it in places where we had been relying on Berkeley databases to offload some database work. We are not some wimpy million page a day site, either. Fotolog is a billion+ pages/month site (35 to 40 million views/day is pretty typical for us). We had recently overcome some significant DB-related performance issues which allowed our site traffic to explode, and it started to bog down again under the heavy traffic load (getting back up towards 10 seconds for a page to load sometimes during the peak periods). The servers were churning away each recreating a list every time when it could easily be shared in the same form for at least 5 or 10 minutes. So we introduced memcache, creating a distributed 30-server cluster with 4 gigs available in total and made a very minor code mod to use memcache, and our peak period load times dropped back down to the 2 second or so range. It has allowed for continued growth and incredible efficiency. I can't say when I've ever been so pleased with something that worked so simply."
