So, you want to run some website benchmarks from your Mac, do you? Well, good news and bad news. The good news is that your Mac already has it installed, but the bad news is that it is broken. If you’ve run the command now, you’ll probably seen the following error message:

$ ab -n 1 http://www.google.com/
This is ApacheBench, Version 2.3 <$Revision: 655654 $>
Copyright 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/

Benchmarking www.google.com (be patient)...apr_socket_recv: Connection reset by peer (54)

To fix this, you’ll want to run the following commands. In my example, the latest version of Apache is 2.4.3, but by the time you read this it may be a newer version, so just in case, download the latest Apache from their website.

ruby <(curl -fsSkL raw.github.com/mxcl/homebrew/go) # install homebrew
brew install pcre # install PCRE, required by Apache
wget http://apache.mirrors.pair.com/httpd/httpd-2.4.3.tar.bz2 # download Apache
tar -xzvf httpd-2.4.3.tar.bz2 # extract Apache
cd httpd-2.4.3 # enter Apache directory
./configure && make # configure and compile Apache
sudo mv /usr/sbin/ab /usr/sbin/ab.bak # backup old ApacheBench
sudo cp support/ab /usr/sbin/ # install new ApacheBench
ab -n 1 http://www.google.com/ # test new ApacheBench

There ya go! This fixes ApacheBench in OS X Lion. I’m not sure if this also affects Mountain Lion.

    I had to symlink the compiler before configure would work:

    sudo ln -s /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.8.xctoolchain

    • Thanks for the tip about the symlink

    On 10.8.2 with Apache 2.4.3, I was unable to build, first due to the toolchain bug above, and then due to another libtool bug. Wasn’t able to figure out how to fix the libtool bug, but I ended up installing ab via AlekSi’s homebrew-dupes:

    brew install https://raw.github.com/AlekSi/homebrew-dupes/064c06248bdd33015e35716e92578f28e2caa06b/ab.rb
