Lilou NDS communication box. Runme. Now, that's fairly annoying. It looks like the TCP WiFi transfers with the "devkitpro r32" is roughly 3 times slowlier than its r21 counterpart (in purple) for the same receiving code. That's especially annoying since it significantly increase the duration of a self-upgrade cycle during development. The new performance (in black, as reported by wireshark) is impaired by regular "waits" of ~200ms before the PC retransmits some data.
And I'm doing the test with a local server here. DS2DS v3.2.
