Please wait...
Anything being routed (especially if NAT is being applied, so that's pretty much all IPv4 traffic from most networks) needs to be forwarded by the CPU.
And guess what: even my cheap little router can saturate a 1 Gbps pipe. This means that the typical residential network user, even an enthusiast, isn't going to notice the difference.
Equipment containing a true programmable switch fabric (such as a Broadcom chip like a Trident or Jericho) is going to be two orders of magnitude more expensive. 10 Gbps ports are entry level for that kind of equipment now.
One of the weirdest things i have ever seen.
Take new router out to closet, all it does is keep power cycling. I thought it might have been something i had plugged into the USB port for power that was pissing it off on boot. ( my security cameras wireless connection point ). So i punted until today for when i was bored. Grabbed a usb plug for the camera thing and tried it again. Nope. Remove all the cat 5 cables. Nope,. still power cycling. Pull it off the battery side ( that is working fine for everything else ) and move it to the surge only side. Nope. Bypass the power "box" totally and straight to 110 outlet. Nope.
Bring it back in the house. Works fine, just like last time.
wtf.
Yes i can get around it....
Option 1 - Move the router "inside" the house. But it also means relocating my 2 mini-servers that are out there now, the router, ups, camera endpoint, cables, bla bla.. so more stuff in my 'computer room/office' to deal with, along with my huge ass AI server box that is in here now. End of world? No. Annoying as all hell, yes. Noisier and warmer in here, yes. Might be a power problem too having it all on one circuit. My AI box can suck up close to a KW at full blast.
Option 2 - Turn off WiFi on current router ( which is the current issue. being flaky now ), and stick this new one in the computer room for wireless only. Would work with less space, but who knows how long the other is going to last since its acting up. And ill need another switch. Id be out of ports and do need a spare from time to time. Short of going wireless on my main PC i guess..
Option 3 - Move to another house that has plenty of room in the basement to do it all. ( lol, id love to do that.. but nope )
and i know an option would be go build one out of one of these multi-port arm boards i have around here that are meant for that, and leave things 'as they are' as far as location and such. But i just bought this stupid thing. Be nice to actually use it.

Yes and no. For example, my little Mikrotik hEX (a USD$50 router) has
a little SoC that includes a small switch fabric, but the only packets
that are fast switched are the ones that don't have any transformation
applied to them -- so basically that's just local traffic coming in and
out of the LAN ports.

This is very surprising to me. Where I work, every product we make has a dedicated routing ASIC on the board. For some reason we don't route through the CPU, even though it would just be configuration or metrics type traffic. That's why I assumed it had to be that way.
Would make it more flexible. But i can see that happening on enterprise level stuff where you need the bandwidth. But home and small office, a cheapo CPU is more than enough to push those bits around.

Even lower than bottom.. considering the CPU In some of the
commodity routers are worse than an RPI.
But the CPU isn't doing the routing. They have some Broadcom ASIC
doing the heavy lifting, and the CPU is only there for configuration.
I suggest you take a look at RouterOS network flowchart.
Lots of operations can be carried out on specific hardware components, ie. if your router has 2 independent switches in its hardware configuration, the switches themselves can manage a lot of the traffic themselves without involving the CPU. However, as soon as you start doing layer 3 firewalling you will get the CPU involved for a high number of connections unless you offload it somehow.
I am not aware of how RPI routers do it, but RPIs have abyssmal IO in general so I am not optimistic.
There, i fixed it for you . lol
To be fair, they do have a good ecosystem, but they always chose the lowest possible arm soc available so they could be the cheapest on the market, but marketed it as 'more capable' so people bought into it, and many were turned off due to the lack of performance, giving the ARM world a bad name for a long time. If they had marketed it for what it was, i ( and others ) would not dislike them so much.
I am not aware of how RPI routers do it, but RPIs are pathetic pies of crap, by design.

Right ... even my little Mikrotik hEX (as I mentioned, a USD$50 router ... you're using it right now by way of accessing this site) has a packet switch on the SoC and will forward packets at wire speed if it doesn't have to apply any transforms such as NAT or VPN or whatever. I like how there's an actual forwarding rule in the configuration for "fastpath" to manage and track what's being forwarded that way. I believe you were the one who turned me on to Mikrotik some number of years ago and I've been a big fan ever since.
Speaking of TP link, they may be banned shortly in the US like Huawei. Even tho officially they are built in Vietnam, and funneled thru a company based in California. And as of yet its just rumor so unsure what 'ban' means. No more selling to state/federal entities? No more selling to anyone? Or an actual purge and if they are detected on the wire, your ISP shuts you off?
i wonder which other brand paid off the feds to get that thru.. None of this is about national security, its all about money. ( i hear they are the most popular brand for home use so mega money coming in to replacements )
Fun part is a psychiatric patient was the one who first told me about them XD
