Hi. When running page speed tests on https://www.webpagetest.org/, I have terrible time to first byte when testing with IE. Most of the problem seems to be negotiating my ssl which is Le’ts Encrypt. I don’t have this problem when testing with other browsers. Any idea how I could begin to address this?
So I learned IE does additional ssl certificate checks whereas chrome and FF don’t. This additional check can be disabled in the browser but Im sure my visitors haven’t done that. Is getting on a hsts preload list the only way to avoid this additional check? Im not sure how other sites with an ssl get around this on explorer because it add a discernible amount to the load time.
I am gradually converting a site to use AmpProject.org templates that are impressive for mobiles and desktops.

How does that fare on IE? IE is my problem because of the additional ssl certificate checks.
Select I.E. from the drop down list box before running the test.
The test showed 130ms to the first byte for about half-a-dozen videos.
That is interesting I will look into it thanks!
I’m wondering if the delay really is because of negotiating SSL.
I was a bit surpized after reading the article linked to in this post
Your screen capture shows 2 resources loading in comparatively slowly in parallel.
Do you know exactly what those two are?
It seems even if you call in script after CSS IE can still want to load the script first.
So there might be something similar happening for you with IE that isn’t happening with other browsers.
Which resources are you referring? Here is a more complete waterfall.
Do you have IE11 or Edge? Could you possible load my site and see if it has a a slow load?
Both.
Looks to me like the delay problem is due to so many CSS files being requested.
IE 11
Edge
I have similar results in Vivaldi dev tool Network, so I don’t know why the online web page test you used would be singling out IE.
Do you really need that page to be making ~100 HTTP requests (of which at least 15 are for CSS files)? I think that’s more the problem than file sizes which all together total ~700 KB
In the IE11 test, the 9.49 s is fully loaded correct? This is a wordpress site. Thus the high number of css files. Im trying to combine them. I did just change some of the ordering in the head, some css files were after script. Im hoping that helps some. Thank you so much form running the tests.
Yes, but I have cable.
So depending on the sites visitors connection it might be better or worse for them.
Yes, despite the number of members that say “WordPress is the best” it does often have its share of problems. Seems most often it’s because all kinds of plugins have been tossed into the mix.
That fully loaded is terrible. Granted most of my images are deferred, but still. I don’t get those times on Chrome or FF. You are right about WordPress, it does have its down points. I’m just not versed enough to code from scratch.
So I went back to http from https to test. My problem is gone. My site doesnt need to be secured for the most part, I was simply trying to take advantage og HTTP/2 and I know it requires a secure connection. I didn’t see much speed adavantage and the the ssl was very problematic for IE. Oh well, why we test I guess. Im’ not sure how other secure sites get around the IE problem.
