I am using landing pages for the first time in our current campaign. It's a mobile lander with 1.5kB of HTML/CSS and a 5kB .png file. Both the HTML file and the picture have been uploaded to two different CDNs (maxCDN and XCDN) but not happy with the loading speed on either. Different speed tools give different results, but they range from 400ms through to 3.5 seconds, with an average of around 1 second across different tools and geos. I thought with a tiny file it would always be quick to load -- are my expectations too high?
It's an AV install offer in Russia, banner CTR is 1-2% but landing page CTR is terrible. Not sure whether our landing page sucks, or whether people are closing the window because it's loading too slowly. Going to split test a lander without a picture and a bit less text to see how it performs. Does anyone have any other suggestions?
How fast do your mobile landers load? And is there anything else we can do to speed up delivery?
Here's some screenshots of pretty typical speed tests on a Russian server. The first is the landing page with a picture, the second is without.

It seems to be 404ing on favicon.ico, which I understand is the little icon that is shown next to the URL. I don't think this is affecting loading speed, but is there anyway to instruct it not to look for this icon? Do mobile browsers even request favicon.ico?

Slightly faster for the lander without the picture. It seems to be taking a while on DNS, is this something I can address? (Edit: I have now handed off DNS to Cloudflare and load times seem a little better)
The problem is at the network level with the time it's taking to look up the domain name and actually connect to an endpoint.
This could be because of the testing system you are using and them not caching anything or their time-to-lookup could just be terrible, especially from the Russian server.
How does it play out if you test repeatedly from a US/UK server?
Testing via Pingdom tools reports loading times as low as 22ms, but the graph still seems to show that it's taking 500ms plus to fully load the page (unless I'm misunderstanding something).

We're also seeing massive click loss from traffic to
edit: Site, not WiFi campaigns are fine
Those results are weird. Something's not quite right.
Click loss is normal but depends on a variety of factors. So is it the app traffic but with carrier connectivity that's dropping a lot of clicks? Is it mainly from a hog placement?
Low lander CTR on it's own doesn't say much. Low relative to what? 5-7% could be plenty for a specific type of traffic/vertical/offer.
PM me your page URL and I'll have a look to see if there's something obvious.
