Hi Simone,

Long time no talk ;-)

Thanks for sharing your experience!

I have experimented with 16Mib and 32Mib.
Even on slow network (VPN) the settings in my patch give me a
boost of 2+ times faster response.

These settings can be overridden by specifying an alternate
value for the corresponding net/system properties, if the
defaults is not appropriate for the application.
If I'm not mistaken curl seems also to be using large
connection window sizes.

best regards,
