Re: [lwip-users] LWIP slow web server only with Windows OS request

[Marco Giammarini]

Dear all,
in attach you can find new capture.
The lwip device is: 192.168.1.123 for OSX acquisition, and 192.168.10.123 for 
windows acquisition.
Anyway, if I put the OSX device into the same network of Win device, the result 
for OSX device is the same (3/4 seconds to obtain the webpage).

Regards,
Marco
