Hi, I’d like to know if anyone is using nginx-1.0.x with mod\_push in  
production to keep persistent connections on a website.  
I’m little scary about the huge number of active connections my servers  
can mantain (10000 or 20000).  
I’m using a DELL R200 with FreeBSD 8.2-amd64 with SAS HD and 8GB Ram,  
using these sysctl:

kern.ipc.nmbclusters=262144  
kern.ipc.somaxconn=65535  
kern.maxfiles=524288  
kern.maxfilesperproc=131072  
kern.threads.max\_threads\_per\_proc=16384

If yes, did you evaluate pros and cons on nginx vs node.js or comet?

Thanks in advance,  
d.

That’s not very many concurrent connections. I’ve seen nginx do much  
more with push.
