I want to like Apache-bench more than I do. Although very simple to use with excellent reporting and widespread support, I keep abandoning it and find myself load testing with Siege. The main reason for this is the use of a url file. With siege, I can quickly and easily hit a file of urls at random, thus getting a more complete test of my app.
ex:
siege -c 100 -t 10m -i -f links.txt
(with the links file containing as many urls as I need)
At first glance, there wasn’t an easy way to do that in Apache-bench. Then I ran into an article describing how to do just that. (and it is easy, no less!)
“ab -n 100 -c 10 http://127.0.0.1:8300/test.cfm > test1.txt &
ab -n 100 -c 10 http://127.0.0.1:8300/scribble.cfm > test2.txt &”( quoted from article above, published on this site. )
I was totally excited to find a solution to the multiple url issue and ready to give Apache-bench another shot. Unfortunately, the results are reported separately and would need to be aggregated by hand, as far as I can tell. Does any one use Apache-bench for multiple urls and have a solution for the reporting issue? How do you evaluate load data for larger scale load tests?
#!/bin/bash
URL="http://myurl.com"
SLEEP=30
URIS=(
"/"
"/aboutus.html"
"/dynamic.php"
"/dynamicmore.php?id=34252"
"/search?q=${RANDOM}&show=all"
"/anotherawesomepageofanything"
)
date
echo -e "Batch Apache-Benchmarking on n${URL}"
for URI in ${URIS[@]};
do
echo "uri: ${URI}"
ab -n 100 -c 5 -A xwander:xwander-awesome "${URL}${URI}"
sleep ${SLEEP}
echo "================================================================\n"
done
just run the script and write the output to a file
then i use meld to compare the results from two files, to see before and after a certain feature or something was added.
incidentally, the script isn’t completely written by me, i got it in a search when going through google
check this out:

haven’t tried this yet but seems exactly what you need.
the problem it’s not randomly selected, but there is a path there that might fix that.
