Slow R2 Put/Upload Speeds

Is anyone else experiencing slow PUT/Upload speeds within R2?

I have a service that uploads files to R2 using AWS PHP SDK, it’s currently attempting to upload a 1.4GB PDF but the script’s timing out due to speeds. I’ve set timeout to 15 minutes which should be more than enough for that size file.

I know it’s not the server speeds as I can download the file from the server within 2 minutes via HTTP.
