Well, that is probably because it's an old laptop. I've installed Malwarebytes on so many PCs and never had one complaint...

A previous posting about this showed many people having issues with it.

Would be interested to see this "post".

Same server, same time, reproducible.

Been like this consistently for a few years. OP I just put this down to the browser / hardware maybe.

Seems Chrome can have issues... I suspect on all the Operating Systems it supports.

Browser-based speed tests take a variable (chunky) amount of system resources to execute.

Therefore the results can vary, depending on how much grunt the base system has, and the optimisations (or not) of the browser and the particular speed test.

Interesting observation. I use an older iMac (still 3.4Ghz quad core i5 with SSD etc - so fine).

In Chrome
Speedtest with my Google profile logged in an syncing: 700Mbps
Speedtest as a guest (barebones) 930Mbps

So I thought, must be an extension, disabled them all, still 700Mbps
Tried a brand new profile from a different account, still 700Mbps

So what on earth are Google doing that would affect the transfer speed.

Hope its not sniffing / traffic analysis.

It might be worth trying the Speedtest app available from the Microsoft Store (free). This eliminates any browser profile issue.
There is also a command line (CLI) version available.

Also in the Mac App Store for the poster with a Mac
https://apps.apple.com/us/app/speedtest-by-ookla/id1...

For Macs: also have Activity Monitor open in the dock, while you're running the speedtest. Seeing the CPU jump to 100% proves that it's the laptop/browser/OS combination which is the bottleneck, not the service from the ISP.

On my dual-core i7 Macbook Pro (2015 model):

* In the browser, my CPU load goes to 100%. This is despite me only having a 300/50 FTTP connection.

* But if I use the Speedtest standalone app, CPU load is much lower and it shows the full speed available.
