 * Hey Futta,
 * We have been getting a massive bill from our CDN provider (maxcdn), so I asked
   them to send me the top 50 CDN bandwidth users for the past 30 days.
 * Two of the biggest users appear to be from WP YT LYTE. For reference, most of
   the top 50 (aside from our big CSS and JS files) are under 500 MB. But you can
   see that the lyteThumbs.php is pulling 311.02 GB. Any idea on how to fix this?

 * you could disable “cache thumbnails locally” (assuming you have that option on).
 * do the webserver logs confirm this is valid traffic, or could someone be “stealing”
   your bandwidth?

 * Hey Frank,
 * Will reach out to my host and ask. A few follow ups:
    1. If we disable cache 
   thumbnails locally, wouldn’t that slow down performance? Where would those load
   from? From YT every time? 2. Is it normal for that .php file to be using so much
   bandwidth?

 * re (1) indeed from YT
 * re (2); yes as the PHP-file delivers the image. so even thought it’s a .php file,
   in reality it are jpg’s.

 * 1. So that would slow down performance, no?
    2. So if I’m understanding correctly,
   it’s only job is to pull the jpg? It doesn’t do anything else of importance? 
   Also, it’s not a placeholder (it’s the actual jpg for the YT thumbnail)
 * If #2 is true, then why would that one image be using so much bandwidth?

 * 1. it would slow down the fully loaded time, but not the onload (the thumbnails
   are loaded after onload), mainly because if cached locally the same HTTP/2 connection
   can be used to fetch it iso having to set up a new connection (dns + network 
   connect + https negotiation)
 * 2. it’s not for one thumbnail, but for all those you have on your site (no idea
   if your site is YT-heavy).

 * Got it, thanks Futta. Could turning off cache thumbs locally theoretically make
   onload faster?

 * no, because LYTE loads thumbnails after onload event.
