off-list and asked how you can change the Win32 memcached settings (port,

see, no way to do this at install time, so I thought I’d share how to do
it. <br>
To install as a service run it with “-d something”, I can’t
remember, but it is documented at <a

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? <br>
<br>
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.<br>
<br>
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? <br>

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