dear,
when i plug my laptop to isp router i can get 700/50, i have link from isp router to ac1900v1 to its wan... then when i connect laptop to ac1900v1 lan i am getting 500/50.
Ac1900v1 is running latest openwrt, there is NAT and also few fw rules... nothing special... any idea why there is 200mbit (download) loss?
thanks
AC1900...
Netgear? Asus?
SSH in to the router and run the following...
cat /etc/config/network
cat /etc/config/dhcp
cat /etc/config/sqm
cat /etc/config/firewall

There have been a few reports of speed drop on mvebu targets with 21.x / master, with some attributing it to the change to DSA with only one CPU port currently in use. I think the more likely explanation would be kernel / mvneta changes, but your reported loss seems greater.
hi, @anon89577378 @anomeome
this is strange, the brand is Linksys ac1900v1
Yes the speed drop is Massive; sometimes i get 500/50 other times 300/50... still not 700/50 what i can get if i directly connect the same laptop to ISP router.
the dump of the config is following>

Appreciate your help.
This is so interesting because everytime someone say “ohh I didn’t change so much” we get this…
Offloading = on.
And this…
And this…
So reset the router and test standard settings and see if the hardware actually works.
Save a backup first so you easily can go back.
Or turn off that offloading because it really feels that we would have half the amount of posts in the forum if we didn’t have that offloading function because everyone complaining over speed have that turned on.
Do you have QOS reserving any bw?
as far as i know no qos
cat /etc/config/sqm
cat: can't open '/etc/config/sqm': No such file or directory
I turned off sw offloading, no change in the speed drop... same stuff.
Your assumption is very strange/weird... whats the connection of router speed with 15 static ip defined as part of the dnsmasq?
Also whats the connection of basic port forward with speed drop? Based on your assumption it means i cant add static hosts into dnsmasq and each port forward degrades router speed... very strange.
I don't think that @flygarn12 is actually suggesting the port forwards or DHCP reservations have any direct impact on the speed/performance of your system (although I could be wrong about @flygarn12's thinking). In my experience, those should have zero impact.
However, I do think it is worth testing with a nearly default configuration if you can. Specifically, by resetting to defaults and only changing the absolute minimum items (i.e. things like PPPoE credentials, if applicable, enabling wifi, and any other truly necessary changes), it reduces the number variables in play. This ensures that there are no additional packages installed and that there aren't minor settings that were changed and forgotten.
To be clear, I'm not saying that the default configuration will magically fix everything, but it might, or if it doesn't, it ensures that your system is in a known state for further troubleshooting/debug. The backup is critical, of course, so that you can get back to your current state quickly and easily.
That network config is the same / similar to what was happening with 19.x.
Edit: A bit more finger pointing at DSA being the issue.
@psherman i do get your point ... i cant try ... but as i said .. that was Fresh install and i edited only what was mentioned at the begging of the comment - so almost nothing in total.
maybe the HW of the device is so poor and it cant handle more then ~500,
any view on this?
thanks
Good article by @dlakelan on that subject...
ML observation may warrant testing a master image, also thread may be of interest to see as to a few more PPS with reduced CPU...
