Issue: Slow SLB_Base_Object->get_file() HTTP API Call

[wpbullet]

Description of Problem

Using Query Monitor I noticed a lag on some of my pages from an HTTP API Call by Simple Lightbox which is taking 2.5809 seconds! I'm very curious what this call is for and why it may be slow. The site is on a Vultr VPS server running nginx and PHP7 so I don't think it's a hosting issue.

Using wp profile I also found these are taking a bit longer than I'd like and are even running on pages where there are no images. I'd like to help optimize these if possible.

With Lightbox active where it should load

wp profile hook --all --spotlight --allow-root --url=https://docs.wp-bullet.com/docs/assets-manager/disable-emojis
