Re: [lwip-users] Increase Speed

[Oscar F]

thanks.  I´ll see the configuration of the network,  and i´ll try to force to use 100Mbps.

But if i want to increase the speed by Sw too, what parameters of file lwipopt.h do you recommended modify?

Thanks again

Oscar

That rather depends on whether it's operating at 10 or 100 Mbps.  This
is probably auto-negotiated, but that may be configurable: worth
checking that you have configured it to do 100 Mbps where it can.

As well as the network hardware being capable you must also consider
whether the CPU you have is capable of delivering that data rate.  This
is likely to be a serious bottleneck for the sorts of CPUs that use
lwIP.
