openssh unix dev - Apr 2007 - SFTP and outstanding requests

I've been looking at the SFTP code and the filexfer RFC (and ended up 
answering my prior questions). I was wondering if anyone had any 
thoughts as to what might happen if the maximum number of outstanding 
requests was increased.

Currently its set in sftp.c at
/* Number of concurrent outstanding requests */
size_t num_requests = 16;

Quick note of clarification. I know you can change this from the command 
line with -R. Mostly I'm just wondering if there are situations where 
increasing it might cause problems.

I'm not sure what you are asking. Obviously, increasing this will cause
more requests to be made before waiting for the first request ACK.

You can change this from the commandline with the -R flag.
