How to simulate slow internet speed to test your application?
My website loads blazing fast on my home computer, but that's probably because I have Verizon FIOS with a 100/100 internet plan. Even when I try to use my cell phone, the site still loads exceptionally fast because I have somewhere between four and five bars of 4G LTE speed.
Unfortunately, when I check the load time for my site in Google Analytics, it is not the 1 or 2 seconds that it takes for the page to load for me, but much higher values such as 5 or 7 or 10 seconds! Clearly, there are probably very few people visiting my site with a super-fast broadband connection.
Since I couldn’t get a clear picture of the actual load time for my site, I wanted to simulate a slow connection on my computer to see which components took the longest to load. If you look online, you’ll find a lot of sites offering proxies and other fancy debugging tools, some of which require payment.
