Invoice Ninja Slow to "Print PDF"

Self-Hosted | v5
1

Hello,

We are running a self hosted invoice ninja docker (Unraid OS) currently running from the web browser. Recently (within the last 3 or 4 days) it has started to take a long time to generate PDFs to print for the customer. It was never instant - But I do not recall it taking this long. It is taking about 10 - 12 seconds to bring up the print screen preview. Also when I scroll down to the bottom of the page to “preview” the PDF it takes at least 10 seconds to load the preview as well.

Does anybody have any thoughts? Where should I start?

(Please note I am newer to servers, Dockers and all of this. Having a lot of fun working on it and learning it. We are now using Invoice Ninja as our primary software at work and everybody seems to love it. Hoping we can find a way to make the PDFs load a little faster.)

Thanks guys!

What are you using for PDF generation? It could depend on that and it could also depend on how much memory you have allocated to your VM.

Thanks for the reply.
I was browsing the forum and I found another post about editing the ENV file and entering different options for PDF Generation.

My question is how do I edit this file? I was able to locate it but it only has 1 line when i open it with notepadd++. App_key=Base (then a key) is the only line in the ENV file.

What direction do I go from here?

Thank you!

Generally, I use Nano, the default editor on most Linux CLI. I know lots of people also like to use Vim or NeoVim.

There should be a lot more information in the .env file than just that. Following is the sample provided by the developers.
