Please use the developer console to see what the holdup is. It might not even be this server if it's a linked script or stylesheet. Also 69 requests is a lot if they're happening simultaneously. A lot of browsers and servers won't let you do more than 2-3 requests at the same time. If you are downloading all 69, 3 at a time, sequentially, that's 23 sets of downloads. At 0.1s each that's still 2.3 seconds.
If you are unable to do this, please let me know what link you would like me to try.
Here you can see me loading Microsoft.com. All the red stuff is blocked by ublock origin. Some of the assets aren't loaded until 20+ seconds after the request! But you can see the waterfall since it's not doing a simultaneous download. This will help you out a lot. If it's 1 thing taking 20 seconds or 20 things taking 1 second, there's a big difference how you approach it.
