Hi, Yarrick:

My iodine server is centos7, currently running iodine and squid services normally, the server's virtual network card IP address is 172.16.255.254; The Win7 client installs the openvpn virtual network card and sets the browser proxy to 172.16.255.254:3128, the web page can be opened normally, and can watch 1080p video smoothly. Win7 client test ping 172.16.255.254 successfully, the average delay is about 150ms.

I currently encounter a problem as follows:

This iodine server and Win7 iodine client are very slow to transmit data through the virtual network card, FTP transfers about 60MB of data, it takes at least 1 hour.

What direction should this problem be investigated?

Is the client close to the server or on another network? Is raw mode used?

iodine is not meant to be very fast. Which way are you transferring the data? Traffic to the client is usually faster.
