c# - Scalability of WCF over NetHttpBinding with WebSockets -

i developing application server requires large amount of connected users (stateful "duplex" functionality, hence sessions). traditionally develop using sockets opposed wcf nettcpbinding due known deficiency in scaling under heavy loads - , heavy loads mean thousands of concurrent sessions , on 100+ calls per second.

however have been reading on place websockets on iis 8+ can handle 10ths of thousands of simultaneous connections.

in lieu of maintainability in team rather migrate wcf if @ possible. simpler develop service application using wcf sockets directly.

can attest such claim? websockets handling large number of connected users (thousands or 10ths of thousands) of simultaneous sessions?

care share examples?
