Is that using the Win32 port of memcached?

I don't think anybody really has much experience running the win32 port of 
memcached, let alone high traffic; however it's great to hear it's been 
tested.

Please try running the new ports (either 1.2.1 or the previous 1.2.0) or 
even the old 1.1.12; the 1.1.13 had some bugs that were fixed in version 
1.2.0 and where not present in version 1.1.12; 1.2.x also uses the new 
features in the memcached core of the 1.2.x branch and thus it has new 
improvements and features that, even though have still not been tested as 
much as the older versions of memcached, should greatly increase performance 
and stability; it would probably be better to stay away from the win32 
memcached version 1.1.13, as it had some major issues.

You can get the win32 ports of memcached at:

Please share your experience with these newer versions.

Kronuz.
