From @Linaro1985's [investigation](https://github.com/openwrt/mt76/issues/628#issuecomment-1001170423), this problem is probably caused by the ethernet driver.
It seems that can be **fixed by mt76 patch**:

Setup
ONT>OpenWrt Router> OpenWrt AP
Router/AP - x2 TP-Link TL-WR850N v2 (mt76x8) (2.4Ghz Only)
Openwrt 22.03.3
According to techinfodepot.shoutwiki.com it support 100mbps on WAN and LAN ports
CPU/Switch/WiFiChip - MediaTek MT7628NN
Associated Stations show 144mbps/144mbps
Using 2.4Ghz n 23dBm 40Mhz (not forced) Manually selected a channel
Is flow offloading enabled?

luci-app-wireguard
Is this thru a Wireguard tunnel?
Try disabling and test - since it's set above the 100 Mbps anyway.

As you found connecting to the ISP gateway (ONT) wifi directly, about 45 Mb true throughput is the limit of 2.4. Also of course you can't get more than 94 Mb on a Fast Ethernet port, accounting for packet overhead.
Setting the QoS slightly lower than your worst bottleneck will improve bufferbloat, but of course the speed can't be increased. With this router you can't use the ISP speed that you're paying for.
RSHARM:
No it is disabled
...enable it.
RSHARM:
Sometimes i get 130 on ONT
Excellent!
