Earlier this morning I decided to do a Windows update.

 

I happened to be using my Task Manager Ethernet speed monitor and saw my 100/20 fibre burst to 327Mbps download for 2 or 3 seconds - Wow.

"It depends" on the LFC.

 

Enable in Christchurch seems to have a less aggressive policer from what I found when I was testing. Was able to burst to 800+Mbit for a few seconds (Up to the first 50MB of data transferred from memory) before having the traffic being dropped on the floor. Chorus were a lot more aggressive and I think policed after 5MB. 

 

That was why with Truenet there were people in Christchurch on Enable Fibre with certain ISPs getting "reported speeds" above 100Mbit as they didn't police/shape the traffic to prevent it being dropped for customers on the 100Mbit plan.

 

http://jonette.co.nz/final-truenet-report-januar.html

 

Hence why "technically" correct you "could" get speeds over 100Mbit / your chosen plan, it wasn't accurate as you couldn't have "sustained data rate" based on your speed.

 

All those reports showing over 100% speeds were never accurate.

 

 

 

Without a correctly configured shaper your international throughput would fall through the floor. So while you may get a slightly higher speedtest / truenet result. When it came to downloading a file further away than Australia (such as US/UK etc) it would take far longer due to packet loss and retries. Hence the experience would be significantly worse.

Windows updates can also come from other computers on the LAN using delivery optimisation. That could come in at gigabit speeds if you have a gigabit network.

Thanks for that info.... never been into the delivery optimisation part of Windows Update before.... It is ON in my setup.

 

My network is all Gigabit.... I was updating my main PC this morning.

 

My 'always on' PC while it has a Gigabit Lan port has the CPU knocking 100% utilisation most of the time.

 

However my main PC could have fetched the update from my 'always on' PC at 327Mbps.

 

Out of curiosity, I will try and figure out the source of my next update for my main PC.
