I have my own proxy system on my ubuntu server.

My setup:
- 5G SIM cards
- E3372h - 607 dongles
- Orico USB Hub 3.0


I am currently using the dongles in cdc_ether modes on my Ubuntu server and getting around 40 Mbps. My SIM card provider has 250mbps and when I connect the dongles directly to my macbook I get 150mbps.

What could be the problem that my proxy speed is only 40mbps?

Measure speed :
1. dongles to the Macbook with the USB hub.
2. dongles to the PC with proxies directly.
3. The same SIM in an Android phone
4. Android phone with this SIM with PC (tethering)
BTW I can't believe these dongles can work on 150mbps. Disconnect WIFI and other sources of Internet while testing.

On my MacBook and Windows pc I get 150mbps with the dongles (without wifi).
On Android phone with SIM card 4G 190mbps and 5G 250mbps
 
What's the upload speed?
I think the maximum download speed from the proxy will be no more than the upload speed from your SIM

on my proxy around 35-40mbps upload.
The SIM card supported by the provider has maximum 50mbps upload (this is with all providers in Germany) and download 250mbps in 5G

and directly VS Hub - did you test it?
What is the mode on Windows\Mac -- cdc_ether or other?
On Linux you can change the modem's USB composition from (your current one) cdc_ether (hilink, with WebApp & dhcp server) to cdc_ncm ("Stick", with cdc-wdm and wwan ports). The latter has no double NAT and might be faster.

Si I guess that's the maximum speed you'll get on your proxy because your upload speed on sim provider is only 50mbs
 
As I remember E3372 can have up to 50mbps Upload speed.
So that would be your maximum speed on proxy.
Usually providers also limit upload speed to 10-50 mbps, while dowload speed could be much faster.
You can try to check the maximum Upload speed using some other device.
 
Could likely be due to how cdc_ether mode handles USB networking on Linux as it's known to introduce overhead and limit throughput. Try switching to switching to MBIM/QMI. If it doesn't work, proxy configuration or SIM provider conditition.
 
i have the same setup, upload and download is at 10mbps.

those dongles can only operate at 4G right? not 5G speeds

i tried the e3372s version which does not have hi-link, it does not seem to work properly. my understanding is that we are using it in the stick function and not the hi-link. i could be wrong
