Thanks for the reply. I have narrowed down the problem to Nordvpn. The degradation is up to 70%. I have notified them but suspect they can or will do nothing. I am wondering if other vpns are the same. Am considering a trial of surfshark.

Thanks Sean for your reply. I had avast running so I uninstalled that. Also, I thought cleaning the fan would help, so I did that. In addition, I tested without NordVPN running. This all increased my speed to what I am supposed to get through the test on the browser. The standalone test suprisingly gives 40mbps lower! Can't say for sure which of the above solved the problem. I will monitor the performance further but it seems speed is quite sensitive to the NORDVPN. Maybe will post later about that.

Thanks again.)

I have had Internet speed problems for about six months. I spent some time about four months ago researching and fixing some settings without solving my problem. Recently I changed ISPs for cost reasons and also hoping to solve my problem. But to no avail. I am supposed to get 100mbps. When I switched, I used stand alone Speedtest and got initially 67 then down to 50. This can sometime be 50 but will usually be around 30. If I measure using speedtest from a browser, I will usually only get from 25 to 30 per cent of the stand alone speedtest speed. So, for 50, I would get 10 from the browser. So, I have sever degradation of the standalone speedtest speed which is itself also only about 50% of my supposed ISP speed. I am wondering if there is any diagnostic tool or utility which might analyse my problem. For instance is Debug Diagnostics Tool any good for my situation? Any suggestions welcome. Thanks. Peter

Thanks for the feedback. I have been trying to narrow down this problem to a few variables only but it is a frustrating business. One recent problem surfaced which has to be dealt with before making progress on any other variables. Today, without any browser loaded but Nordvpn running, I ran speedtest and got 10mbps, all references are download speeds. I then turned off Nordvpn and ran speedtest and got 120mbps. I turned Nordvpn back on and got 10mbps. I turned Nordvpn off and then got 120mbps. AND I have noticed that with some testing I was doing previously with nordvpn on/off, I did not get such a severe degradation. So, no browser running but nordvpn, there is a 92% degradation of download speed. With no browser running and no Nordvpn running speed is 120mbps. I have also done a lot of testing with other configurations, FFsafe, FFregular, Chrome, VPN on/off but this is the first time I am experiencing such a severe degradation through NordVPN alone. Until I solve that problem further testing is nailing JELLO to the wall. So, I suggest either: 1. NordVPN is incredibly inefficient or possibly 2. My ISP detects NordVPN running by its server address and then throttles my speed. Thanks for any suggestions. Peter

I have run a number of tests since last posting. I am concentrating on the FF browser as the main bottleneck. I am ignoring any interference from VPN and not doing any testing with it on. I ran tests using FF Portable on my desktop and did not find any difference than regular FF. The regular FF has only one extension active. I use speedtest alone and usually get 120mbps. run other tests to compare at about that same time. Consistently with regular FF, the best is can get is 25mbps. But usually I get 10-15mbps. Thus, at least 75% of potential speed at least is being lost using regular FF. I also loaded FFPortable on to my desktop and most times actually got a worse performance than regular FF. I have also tested using just a basic, unmodified Chrome and get about the same results. And on some occasions, with 120mbps through speedtest, I will get below 5mbps with regular FF. Absolutely dreadful! So, I guess my basic question is what should the normal degradation of internet speed be by using FF or any other browser? Normally, I am operating at about 1/10 of the 120mbps internet speed available.

Thanks for the information and suggestions. I will try all the items listed and post back with my results. Thanks. Peter

Hello from Nova Scotia, Canada. Recently, I upgraded my internet service to 100mbps. Installed a new modem/wifi router. I use a laptop for my internet. No other devices online other than a monitor. For testing, I am using the Speedtest app by Ookla which I can run independent of the Firefox browser. For testing with the browser, I am using testmy.net. I am finding a LARGE discrepancy between the download results I get with NordVPN on or off. The difference is around 1/2 performance, that is say 50mbps on/100mbps off. That is testing independent of a browser. Then I am finding a HUGE difference between Firefox browser on or off. This difference can be up to SIX TIMES, that is testing through Firefox browser, say 20 mbps, and without Firefox, 120mbps. So, for starters, since I can get 100mbps at times, my hardware all seems to be ok. The first major bottleneck then seems to be Firefox 75.0. Once, that bottleneck is solved the second major problem is NordVPN, at times, cutting download speed by 1/2. I would like to know if these discrepancies are normal. If not, how to solve the Firefox problem first and then the NordVPN slowdown. I have researched these problems quite a bit and other than some minor tweaks can't find anything that would result in these major declines in download speeds. Thanks. Peter
