my script using netmiko works fine on linux server in Lab, but not working remotely from my laptop through VPN

[linfeng16]

The target devices is hp_comware device, I run it from the linux machine(ubuntu) in the lab where the target device resides, it worked perfectly, but when I run the same script remotely from my MacBook through a VPN , the ssh connection ok, but the output from the device took long time, caused read timeout, even after I changed timeout to 100 secs, still not working, I thought may be network too slow, I tried ssh to the device from my MacBook, and run the same CLI commands, it responded right away, looks like not much delay, why with send_comand() the output take long time to get the output from the device? any ideas?

here's part of my script

with open(file_name, 'w') as f:
    for cmd in cmd_list:
        f.write(net_connect.send_command(cmd))
    f.close()

the cmd_list:
"display irf topology",
"display irf link",
"display irf configuration",
"display irf-port load-sharing mode",
"display mad verbose"

here's sample of the output when it works on the linux server:
==============================display irf topology==============================

How about increasing the read_timeout here?

        f.write(net_connect.send_command(cmd, read_timeout=100))
