SignalR performance

问题:

We have a web-based game (SignalR for communication), our workload will be:

• 5,000 - 20,000 concurrent client with 0.5 - 2 messages/client/second ~= 10-40k messages/secs

with the following server is there any problem handle the load (assume that signalr has 80-90% cpu) ?

• dual hex-cores L5639 (2.13Ghz)
• 24G Ram
• windows server 2012 standard

(with long-polling we can easily do that @ 5-10% cpu)

As much as I dont want to write it, "it depends" is very much accurate here. SignalR can scale way beyond your requirements. Damnie Edwards (co-creator of SignalR) has got 150k connections from a single 10GB server though:
