3This is a port of Jason Thorpe's kttcp tool for testing network
4performance for in-kernel applications (like NFS). The tool consists
5of a loadable module and a small user-mode application. Beware
6that you should match the kernel module to the kernel it is to be
7used with. By default SYSDIR is set to /usr/src/sys in Makefile.
8You may want to change that.
10To use the tool do something like on each of two machines:
132. su; make install (installs module and kttcp in /usr/local/bin)
143. kldload kttcp
184. kttcp -r on one machine
195. kttcp -t foo on the other machine, where foo is the
20 machine where #4 was done.
22kttcp w/o arguments gives usage. Otherwise the source is your
23friend. Beware that the kernel code must mimic soreceive and sosend
24for results to be meaningful.
