Can it happen that they have a newer (better) ethernet driver? It would be so good to get rid of the crapy TCP performance...Originally Posted by lly
E.g. TCP typically uses ~25% more ethernet frames (due to ACKs) than UDP (in large block transfer) and maybe newer driver has interrupt coalescing or some other trick (I don't know what is possible with this particular Broadcom chip).
Btw I've found some interesting AHB description (some other chip vendors use it+separate ethernet for WAN and LAN no VLAN tagging thus sharing bandwidth).
MIPS74kc may have ~30% advantage in CPU architecture compared to MIPS24Kc and higher clock but the SoC chip may not be that shiny as Broadcom states (or would like to see).
And Broadcom's attitude towards open source developers simply shocks me after all of this.
All of my respect goes to lly, theMIROn and other developers who have done such an excellent job despite the difficult situation.
Update: One more question, would TCP/UDP checksum calculation offload possible with these chips (or is it already used), so that MIPS CPU is not loaded with this?
