Performance of Velocity distributed cache

I was looking for some numbers on performance and throughput of Velocity.
  • First of all here is some extensive performance data from Microsoft Velocity team blog: http://blogs.msdn.com/velocity/archive/2009/04/21/more-performance-numbers.aspx

  • My own test (single cache node, single client on a neighbor LAN computer - sequentially storing 100 .. 1000 instances of the same data into the cache) shown time of around 14-18 ms (per chunk) when storing data chunks of 100K up to 1Mb.

The requested upgrade is not supported by

Proxy should be updated...

No connection could be made because the target machine actively refused it...

Just a self-reminder... Could be caused by WCF security configurations. Either set Binding→Security→Mode→None or if Mode is Transport - then add Windows credentials of user running the service in security config section.

The server has rejected the client credentials - WCF Exception

Control Panel→Administrative Tools→Local Security Policy→Local Policies→User Rights Assignment→Access this computer from the network
Now add Authenticated Users if your services runs as an application or Network Service if it's service.
