Hi,



I'm playing around with a simulation, in which many thousands of IP

addresses (on interface aliases) are used to send/receive TCP/UDP

packets. I noticed that the time of send/sendto increased linearly

with the number of file descriptors, and I found it rather strange.

To better understand the reason for this problem you should first use
oprofile to profile the kernel. This will give you the hot spots of the
kernel, where the kernel (or userspace) spends most of its time.
