Hey, I'm lead web developer for the largest e-commerce shop in northern Europe, Komplett, the largest shop is www.komplett.no <http://www.komplett.no/> , but we have shops in most northern European languages, for example www.komplett.co.uk <http://www.komplett.co.uk/> . Our core platform is based on MS tech and we use memcached to cache all our product info (as XML). Two Win32 memcached 1.2.1 instances with 1GB cache each, with about 700.000 items in each cache at any given time. Yesterday we served about 1.2 million pages.
We've had no problems whatsoever with the Win32 1.2.1 memcached version since we migrated to it a couple of months ago. At first we ran memcached on a Debian box, then we tried a VMWare appliance (Hermes), but Hermes crashed every 3-4 days with out of memory errors. The Debian box worked great, but Operations wanted us over on a pure MS platform, so we had to move it. So I want to extend a big "thank you!" to everyone involved in the memcached project and especially those porting it to Win32 and making binaries available, you have a great project here and you run it well! (Looking forward to a Win32 port of 1.2.2... :-) ) Let me know if you want to know anything more specific about our setup and I'll try to answer.

Yup, thanks mike, I couldn't agree more. Facebook is just awesome. I only really asked about myspace because I know they are a microsoft shop and therefore another website that is MS technology based using memcache would help just as much. Thinking on it now I should have posed the question: What MS Tech based companies are using memcache? I love memcached myself, it is so easy and powerful. And yes I appreciate Steve's posts about Facebook and how they are using memcached, the information is very helpful. I've got the win32 binaries working with the .NET client tools from the danga website. It all looks to work just as good as the *nix versions, does anyone have any experiences to the contrary? thanks again!

Myspace was at the top of the list for .NET sites. Any details > are greatly appreciated. myspace should not be used as a technical model for anything. imho, with as much capital as they should be able to use, the inconsistent and completely buggy interface is uncalled for - especially going on for this many years. facebook would be a much better model. not only is their site clean, consistent, (and uses memcached i might add) but they expose APIs now and seem to generally know their technical stuff. exposing APIs in my mind is the next step when you have successfully been able to please users with your frontend interface. (some people may disagree, saying APIs are nice because other people can make their own interfaces and you don't have to change yours) to me myspace was built not to scale properly and ever since has been struggling to do anything to support the load. i mean come on - it started with coldfusion. did they really expect to be one of the busiest sites on the net starting with that? :) i really don't think they've put in enough funding or the proper resources from what it seems like, unless they have a secret completely rewritten version in the works. not only does facebook use memcached, but steve is one of the most active posters it seems and him/the team he works with has made numerous improvements and i'm quite sure runs one of the largest (if not the largest) memcached clusters anyone has ever claimed that i have seen.
