2This is a port of Jason Thorpe's kttcp tool for testing network
3performance for in-kernel applications (like NFS). The tool consists
4of a loadable module and a small user-mode application. Beware
5that you should match the kernel module to the kernel it is to be
6used with. By default SYSDIR is set to /usr/src/sys in Makefile.
7You may want to change that.

9To use the tool do something like on each of two machines:
10
111. make
122. su; make install (installs module and kttcp in /usr/local/bin)
133. kldload kttcp
14
15Then:
16
174. kttcp -r on one machine
185. kttcp -t foo on the other machine, where foo is the
19 machine where #4 was done.
20
21kttcp w/o arguments gives usage. Otherwise the source is your
22friend. Beware that the kernel code must mimic soreceive and sosend
23for results to be meaningful.
