Peter [and Q],
Thanks for your reply. Does your comment also apply if I'm a Carbon app.
running on OS X and using OTOptionManagement() to change XTI_SNDBUF and
XTI_RDVBUF? It seems to be the case from my testing. I didn't see any
improvement until I changed the kernel variables using sysctl.
-d
ps. Also, it's odd but when I call OTOptionManagement() on a synchronous
endpoint I get a return code of zero. I then check the status field for
T_SUCCESS, T_FAILURE, etc. and I see neither. In fact status remains as I
initialized it [0].
