Hi guys, long time no speak.

I've recently moved home and just had idNET 2gig (up to 2.5Gb) installed, currently getting around 1.3 to 1.5Gb on the download and 1.9Gb on the upload... As its just been installed today, any suggestions on anything I should do to optimise the speed on the download?

I have no idea of MTU settings, tried leaving it at the default settings on my OPNsense box and then manually setting 1492 etc. I googled around for MTU settings on idNET FTTP but I cannot find any good answers... Only stuff for DSL and FTTC.

Any suggestions on what I could do?

Cheers guys

Probably ask yourself if you really need all that

I mean, i'm paying for it. May as well try and get all of that, if I can't for whatever reason that might be then i'd consider calling idnet to downgrade my package to something that caps out at my max capable speed.

What speed tests have you tried?  I'd suspect you're more likely hitting limitations of the test itself.

speedtest.net
nperf using a 10Gig server (the one you see posted above)
fast.com

All report more or less the same download and upload as each other. I've got my mate coming over in a weeks time to clean the fibre ends as hes an engineer for CityFibre.

You're connected to the PON at nearly 10Gb up/down with that fibre. It passed light level tests. It doesn't need cleaned.

If you dont like not hitting line rate downgrade to 1gig/1gig ?

Have you tried testing on multiple clients at the same time and measuring the bandwidth use on OPNsense?

How powerful is your OPNsense box?  Do you have any QoS enabled? I wonder if NAT rules could somehow be reducing download throughput while not impacting upload?

Personally, I'd still consider a 50% increase over the lower package a win as the goal for me is to never quite max it out so QoS is not needed to reduce bufferbloat.

I wanted to wait until my new OPNsense firewall arrived with an Intel N100... and well..




As you can see, a huge improvement!

That's more like it.

what were you using prior?

[sof006]

what were you using prior?

Intel N5105 with Intel i225-v NICs

This new box is Intel N100 with i226-v NICs

[Alex Atkin UK]

That's definitely curious as I was under the impression the N5105 could handle 2.5Gbit NAT.  I only upgraded to the N100 to give a bit more power to OpenVPN as I've had problems with Wireguard.

I thought it would be fine as well, I was running iperf on opnsense and getting around 2.2/2.3gig benchmarking from my desktop but when I finally got my internet installed I saw significantly less, read somewhere online that apparently PPPoe can be quite heavy?

[meritez]

PPPoE is incredibly heavy, got some Cavium Octeonplus devices here that can do PPPoE hardware offloading, without the throughput dips to around a third of total throughput.
