Hi Nikos, I tried to comment out the compression attribute in config file. The test result is very close to the tun's TX. I think the behavior of my end is caused by downloading an easy compressible file that comes from a speed testing website. That make sense I have ten-fold of the value comparing to the log. Thanks a lot.
BTW, I'm curious about the client side when I have previous exercise. What is the actual byte the client received when the server send a compress data? In my previous case, is the client actually receive 1.64MB from server?
