Nginx Speed Limitation

Great. Thanks for the help! I managed to code prototype in less than 100 lines of code (including caching).The promised guide is on the way :)On Saturday, 21...

Nginx Speed Limitation

masterzeus143

Do nginx have any speed limit? while transferring image file or any file to user end?

I have a high speed + highly configured server. but while sharing image to users in my chat room. It takes more time to load the images.

But once those images are cached in browser after first time open. It loads faster than first time ( thats what cache is).

But i want to figure out, is there any speed limit in transfering files? to users enabled in default in configuration?

There is no speed limit, other than your hardware, your OS, your runtime libraries, and the algorithm and options used by Nginx. Which basically means yes - there are lots of bottlenecks.

Understanding which one you are hitting, and whether the speed is reasonable or not, requires a lot more measurement and data.

I've never found Nginx to be the bottleneck in any of my use cases. Which doesn't mean it can't happen - but it's basically always something else first.
