Tricks to make it faster?

[mikealche]

Hey there!
What a fun project!! I'm having loads of fun using it.

I want to render a page where there are many memes (well 12 really) , and this seems to almost take down the deployment (the cheapest Heroku Dyno).

What tricks can I use to make it lighter on the server?
Specifying smaller dimensions?
Upgrading the Heroku Dyno?
Thanks!

https://api.memegen.link is running as a single basic Dyno and handling about 2k requests per hour.

For the provided Procfile, the following environment variables are set:

MAX_REQUESTS=400
MAX_REQUESTS_JITTER=50

It's also running behind Cloudflare to cache images, but that shouldn't impact server performance for new images.

Thanks for the tip! yesterday I've added those env vars.
However, Heroku keeps restarting bc of memory quota exceeded. (each red box in the above graph is a critical event that shuts down the Dyno)

Could there may be a memory leak somewhere?

It's possible there could be a memory leak, though I suspect that would be in the image generation library (Pillow). Any investigation into that would be appreciated!
