Built myself an automated speedtester thanks to Jeff Geerling. Initially it was to diagnose a problem which it helped with very well. Everything seems to be running pretty well now. I have a fairly new 900Mbps download connection with 100 Mbps upload.
The speedtester uses speedtest.net every 5 seconds and records the result. It averages the results out over 7 days and I currently have 5 days of good speeds and it is showing 666 down and 96 up which as I say is pretty good, should be a bit better when I have a full 7 days of data.

The issue (if it is an issue) is the occasional spike, rarely but on occasion the download drops below 100Mbps and there are other more minor fluctuations.

Is that just the way it is? or should I investigate further - how?

Thanks

I think that necessary/unnecessary is irrelevant, I had noticed it was fluctuating, it was wildly fluctuating initially so I wanted to get a 'picture' of how bad that was, this has shown me that.

So, what you are saying is that the minor fluctuations now are just the way it is? Live with it. Fine, I'll do that - Thanks
 
Nothing

But if it showed 860 one minute and 200 the next and so on and so on then I would open a case. As I say I had a very volatile connection for a while which - using this - I tracked down to my router. I still don't know why exactly but I know it was the router and I solved it.

I just left it running, it is by default set at 7 days so I plan to run it for 7 days to see the trend
 
One thing I have learned from having the 1Gb connection, I expected it to be snappier but it is not, not any different really from my 80/20 FTTC but it does download a lot faster.
 
No and No

Again if the connection was constantly going from 860 to 200 then I would expect the ISP to do something - I know that is not the case so I am not bothering the ISP.

I woud imagine the weeks worth of speedtests would equate to downloading an Ubuntu iso, or maybe 2.
