- Subject: Max no of parallel SSH sessions with Cygwin SSHD
I am trying to use Cygwin SSHD in my project. I have defined a
subsystem under SSHD which gets accessed by the client.
Each subsystem invocation spawns 3 processes (1 sshd + 1sh + 1 tclsh).
I have observed that on WinXP only 22 parallel sessions are possible
whereas on a Win2k3 server 48 parallel sessions are possible. Both are
of a similar hardware configuration (3Ghz CPU, 2GB RAM). After which
it seems like some resource allocation limit is reached, though there
is a lot more Memory and CPU available. I have tried increasing the
heap allocation but it does not help the situation.
1. My question is that why is there a difference between the 2 OSs ?
2. Does XP have resource allocation lower limits than win2k3 server ?
3. How can this be overcome ? (some OS settings ..)
