Is there a way for speeding up a PPPoE connection? I'm finding it takes quite a bit of CPU overhead compared to not using PPPoE. My router can reach 1gb/s NATed speeds on IPoE in both directions. However, when testing my router on my PPPoE 500/500 mbit fibre connection, the upload speeds can only do…

[image] lucize: I think is already using kernel mode, try with fasth-path, there is a pr already open I’m in the same boat with wrt3200acm. only ~750mb/s instead of 900+ on pppoe Will fastpath also speed up PPPoE encapsulation / decapsulation? I thought it only improved NAT performance?

on 1043nd v1 pppoe without fastpath I have ~190mb/s with fastpath ~350mb/s so yes, NAT is the problem, I think pppoe in LEDE is optimized as much as it can be

The big difference is that your router is a single core. Bringing down the NAT CPU loaf should leave more for PPPoE. However, my router has 4 threads and is at around 20-25% CPU idle while bottlenecking my upload speeds. So either PPPoE isn't properly multithreaded, or the bottleneck lies somewhere …

it was just an example of how can scale fastpath, I'm using a wrt3200acm, as main, and it can't do gigabit on pppoe, none of the dual core cpu is used at 100 (60% max), and htop shows kernel load, not userspace load, but is almost double than yours on speed edit: maybe i'll test fastpath on it just…

[image] lucize: edit: maybe i’ll test fastpath on it just to be sure If you do, please let me know the results! Very curious about those :slight_smile:

ok so with fastpath on pppoe [image] Speedtest by Ookla - The Global Broadband Speed Test Test your Internet connection bandwidth to locations around the world with this interactive broadband speed test from Ookla

[image] lucize: ok so with fastpath on pppoe Very nice speeds! What internet connection speeds are you using? Fastpath does seem to allow you to cap out your download speeds now :slight_smile:

best effort 1gb/s down 500mb/s up ~10$/ month :smile:

[image] lucize: best effort 1gb/s down 500mb/s up ~10$/ month :smile: Your router should be plenty fast to max out that 500 mb/s, right? It's weird you are only getting around 450 mb/s. It's similar to my DIR-860L without fastpath.

is 450 from 500, and the test is not accurate for down is 900 from 1000 so it's ok with fastpath but only ~750 without it
