Suddenly very slow to generate packing slips

How exactly are you importing the Asian font? Have you enabled font subsetting in the settings?

Hi Ewout – thank you for your reply.

I import with these two lines in style.css:

@font-face {
	font-family: 'NotoSansJP';
	font-style: normal;
	font-weight: normal;
	src: url('https://mywebsite.com/wp-content/themes/theme-child/woocommerce/pdf/nohinsho/fonts/NotoSansJP-Regular.ttf') format('truetype');
}

@font-face {
	font-family: 'NotoSansJP';
	font-style: normal;
	font-weight: bold;
	src: url('https://mywebsite.com/wp-content/themes/theme-child/woocommerce/pdf/nohinsho/fonts/NotoSansJP-Bold.ttf') format('truetype'); 

Then

font-family: 'NotoSansJP';

in body.

I tried the “font subsetting” setting but it threw an error. I’m going to try again now with all caching/minimisation turned off.

Actually…

I just saw your recent update. Updated to 2.4.2 and it seems to have resolved!

Still doing some testing but I’ll mark as resolved for now – thank you!

Glad to hear it’s resolved! I can’t think of what fixed the issue in this update though.
I strongly recommend changing the https://mywebsite.com/wp-content/ to a server path, because otherwise it’s loading it as an external source (over the internet) even though it’s on the same server – that will definitely slow things down. Our documentation explains how you can do this: Using custom fonts

Thank you! I have updated the path as you suggested – much quicker!!

…and I still don’t know what the root cause was. Maybe upgrade to 2.4.1 didn’t go well on my side? Really not sure.
