Test TTFB response times with siege
As I’ve recently changed some of my personal server’s infrastructure I wanted to
test the response time of it. One tool that I’ve found useful for that is
Why do I write this post and not a post about what happens after the first server response
lower hanging fruit to pick there. But now I wanted to test my new
puma setup, right 😏.
Next learning is that I should focus on “frontend” performance, if that’s an expression. Meanwhile I’ll link a resource about performance from a user’s perspective to compensate.
If not changed in the settings,
siege will parse the html and pull down all
the images, css and other external content that is referenced. I don’t know exactly
where they draw the line. And to change this, you need to edit the config file (please
introduce a options argument). Check where that is located by running:
Somewhere down there there’s a line saying:
resource file: /Users/joel/.siege/siege.conf
Go into that file and change the
false like this:
parser = false
And then you can only focus on the server’s response time (TTFB), all the other stuff I think there’s better tools for the job. Your browser’s developer tools for starters.
This will try to run 5 concurrent clients with 5 hits each:
siege https://bolmaster2.com -c 5 -r 5
It will show you the current requests being done and then show you a summary like this:
Transactions: 25 hits Availability: 100.00 % Elapsed time: 3.11 secs Data transferred: 0.04 MB Response time: 0.30 secs Transaction rate: 8.04 trans/sec Throughput: 0.01 MB/sec Concurrency: 2.38 Successful transactions: 25 Failed transactions: 0 Longest transaction: 0.48 Shortest transaction: 0.16
