After moving my website to VirtualMin on my own server, I decided to do some speed checks, and I noticed before even doing the speed checks that loading the website on mobile takes MUCH longer, which makes no sense to me as the WordPress theme is dynamic (I made it using bootstrap 4) so its not like wordpress is giving mobile a differnnt theme, but on desktop the "initial server response time " is much faster, what could cause this?
Response time depends on DNS, the server itself, the location of the server relative to the server from which the response is being measured and then lastly on how you have configured the CMS. So when you say “After moving my website to VirtualMin on my own server…” the operative word here is server. Get a better server and you will get a better response time.
You have for reference the PageSpeed Insights for calport.com which is hosted on a Virtualmin server in India on an AWS t2 medium instance.
Pirates MineCraft… thats COOL man… well I don’t play MC but still
Now, there are things you are not telling us. Is your own VPS server on the same Webhost as it was before? Is your own server configured the same way? Do they compare performance wise?
As Calport points out there is always a difference between networks, you have the chain of links accessing the site which may be different if you connect via phone or via computer. It should however be similar, if not the same, if you connect both devices from the same network. Then you have things like browser on the phone, how fast the phone is, how optimized you site is for phone browsing… etc…
Well, I admittedly dunno a lot about the server config, or what exactly to look for, but I do know looking more in to you WP setup could help. Me and my son-in-law do a bit of that and personally I would rather dump WP all together - ludicrous moneygrabbing - but I have learned there are many things to look at in regards to engine optimization. I won’t recommend any since 99% are moneygrabbing schemes, but some are better than other. For an analysis, also moneygrabbing, you could look at GT Metrix
Do you monitor Cloudflares outages? Cause there are…
One thing hit me in PHP setting, OPCache… forgot about that, but It goes for the entire site, not just any potential Mobile version. And enable gzip…
Well on my end point your site is indeed slow - never been there, so no cache files for me, also I am testing it from EU (behind the waters) - on UK side. I also did checked where you hosting your server and its in CAnada so in USA you should be fast if you coded your theme well and clean with as much less junk as possible. I did my theme as well as my blog is running on wp but I have no cloudflare or any cache enabled yet my speed results in USA are very different from yours. Have look at screenshots I’ve made from my end point…

Desktop:
In a world we living today no matter what cache capabilities you have, sometimes you trigger filters on those optical cables means they intercept everything and copy it somewhere specially if you your domain is piratemc be it mc or be it hungry pirate in kitchen… also if you live and focus your website to eu or any other country outside of usa - you should move it out as even via fibre optics under the ocean and those nsa filters - meh you would be slower about 3 to 4 seconds in best. I can have look at your wp theme with you if you want even via whatsapp call. Perhaps problem is in theme or some plugin… always use less plugins and cleanest possible themes (code those by your self if possible) and keep your server closet to the country of your business interests.
my last point would be enable gzip on apache and optimize sql db of that wp and if your hosting does support ssd-es use them!
feel free to pm me at any times… or reply here or something if you are interesting.
