HttPerf

First, compile httperf for your platform. It works just fine under 32 or 64 bit. Use file to verify the binary matches your platform. <geshi lang="bash"> $ file /home/ec2/bin/httperf /home/ec2/bin/httperf: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.8, dynamically linked (uses shared libs), not stripped $ file /usr/local/bin/httperf /usr/local/bin/httperf: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), for GNU/Linux 2.6.8, dynamically linked (uses shared libs), not stripped </geshi>

You'll want ssl compiled in. You can either check to see if the '--ssl' option is available in help, or better yet, check to see if the executable links to the ssl libaries. In Ubuntu I had to make sure I had 'libc6', 'libssl0.9.8', and 'libssl-dev' installed before compiling.

<geshi lang="bash"> $ ldd /usr/local/bin/httperf libresolv.so.2 => /lib/libresolv.so.2 (0x00002b3181afe000) libnsl.so.1 => /lib/libnsl.so.1 (0x00002b3181d13000) libssl.so.0.9.8 => /usr/lib/libssl.so.0.9.8 (0x00002b3181f2c000) libcrypto.so.0.9.8 => /usr/lib/libcrypto.so.0.9.8 (0x00002b3182175000) libm.so.6 => /lib/libm.so.6 (0x00002b31824f7000) libc.so.6 => /lib/libc.so.6 (0x00002b3182778000) libdl.so.2 => /lib/libdl.so.2 (0x00002b3182ad3000) libz.so.1 => /usr/lib/libz.so.1 (0x00002b3182cd8000) /lib64/ld-linux-x86-64.so.2 (0x00002b31818e0000) </geshi>

I ran a quick test against Amazon to get an idea of the capacity of my client machine. Looks like I can sustain about 45 conn/s and 455 req/s. <geshi lang="bash"> $ httperf --timeout=5 --client=0/1 --server=www.amazon.com --port=443 --uri=/favicon.ico --rate=60 --send-buffer=4096 \ --recv-buffer=16384 --ssl --num-conns=500 --num-calls=10 httperf --timeout=5 --client=0/1 --server=www.amazon.com --port=443 --uri=/favicon.ico --rate=60 --send-buffer=4096 --recv-buffer=16384 --ssl --num-conns=500 --num-calls=10 Maximum connect burst length: 5

Cygwin

Httperf works great from Cygwin. It's not a standard package, but it's easy to build from source. The usual ./configure && make && make install works fine.

The only caveat is that you can't use the '--hog' option. This option allows httperf to use non ephemeral ports (in the range from 1024 to 5000). If you use the --hog option, you may get this error:

<geshi lang="bash"> httperf: connection failed with unexpected error 106 </geshi>

Slicehost

I ran a quick test again my own host. Unfortunately, the host I ran it from is in Australia, and is on a slow DSL line.
