netperf.sh
Usage: netperf.sh <server>
server machine running ttcpserver
when run and if netserver is running on the machine will run the following tests
- 8K send (what is typical latency for an oracle block transfer)
- 128K send (throughout test)
- 1M send (throughout test)
- 8K receive (what is typical latency for an oracle block transfer)
- 128K receive (throughout test)
- 1M receive (throughout test)
output

columns
- mn_ms - minimum latency ms
- av_ms - average latency ms
- max_ms - maximum latency ms
- s_KB - send KB per operation
- r_KB - receive KB per operation
- r_MB/s - MB/s received
- s_MB/s - MB/s sent
- p90 - 90 percentile latency
- p99 - 99 percentile latency
- <100u , ... , >1s - latency buckets, ie histogram of latency
to get all the output netclient needs to have the histogram option.
On Open Solaris I did the following
vi ./src/netlib.c
changed
879a880,881
> void stop_timer();
./configure --enable-demo=yes --enable-histogram=yes --enable-intervals=yes --enable-omni=yes
make
I was also missing the math headers, so got them and put them a local directory
export CPPFLAGS=-I/khailey/include
./configure --enable-demo=yes --enable-histogram=yes --enable-intervals=yes --enable-omni=yes --includedir=/khailey/include
make
