Interestingly, if I go over about 30-40% utilisation on my PC sending data (at 1gbit link on realtek 2.5gbit NIC) I get an extra 5-15ms of latency (LAN latency) as well as much higher CPU usage,

Are your drivers up to date? I was getting low upload speed and thought my drivers were up to date but turns out the motherboard manufacturer doesn't offer the latest drivers on their website. Had to go to the NIC manufacturer website to get them instead then the issue was solved. https://www.realtek.com/Download/List?cate_id=584

EE are trialing a new router which has all 2.5G ports, hopefully will encorage router makers to do the same.

I get full throughput, just it affects the latency, and yes on newest drivers.

It is just a rubbish low cost onboard implementation.

I would not use any equipment that has Realtek NICs. They are generally low budget and this behaviour is one of the reasons.

Intel 225/226 ideally which even the budget Aliexpress specials use so there is no excuse cost wise to use anything else.

I would *not* use any equipment that has Realtek NICs?

Oops. I have edited to correct.
