+# ab (apache bench) and Gnuplot
+Two scripts:
+
+* `ab.sh` runs your ab benchmark. Specifiy requests, concurrency and URL
+* `plot_ttime.sh` generates graphs with Gnuplot (total time)
+* `plot_ttfb.sh` generates graphs with Gnuplot (Time To First Byte)
+
+Web links:

+* [Apache Bench and Gnuplot: you’re probably doing it wrong](http://www.bradlanders.com/2013/04/15/apache-bench-and-gnuplot-youre-probably-doing-it-wrong/)
