Performance Benchmark?

[quintonparker]

We run a large-ish ecommerce store and we use varnish devicedetect for millions of requests per month. We're able to serve the full request (include a devicedetect call) from varnish in as little as 1e-4 ie. less than a millisecond

i guess this is in part due to pcre jit which should be enabled by default in most varnish installs

Wow, thank you for the prompt response!

So in your option, using this script to detect a device will not take 125ms, in fact, in your experience it should take less than 1ms!? This is awesome, I must try it and although I will close this issue, I will update it with any benchmarks I get from my app with mobile detect in place.

Cheers!

You're welcome. You can even apply an optimisation on top of that by instructing browsers/agents to save the result as a cookie and so you can bypass the device detection and use the value from the cookie instead

By the way, I just realized that to benchmark it, I do not have to change my application code. I just installed it on varnish and checked if its working by manipulating the browser agent in Chrome console. After confirming that it was working, I compared the load times before and after installation. Your 1ms (at worst) seems spot on!

To integrate this, I must however, change alot in my app but make no mistake, it already seems totally worth it! Thanks.
