Openwrt has a very low performance on the board Livebox (DV4210) bcm6348. Every active process raises cpu to 100 wich results in a very bad performance.
I took wget as a reference, downloading a big archive through ethernet to /dev/null. Whereas in the original Inventel's firmware (kernel 2.4) it behaves good enough with a transfer rate of 2.4 M/s, with openwrt I can only get 700 k/s and consuming 100% of CPU slowing down the entire system. Both transfers are done under same conditions and without routing. This is not only a wget problem, also luci or other apps are simply unusable.
I did perform an oprofile test after running wget on openwrt, though I don't have any skills to detect faults.
I was trying to dig for a long time where is the problem, no results. I tried to do some things, like disabling the "wait instruction" in the sources without success. Also looking at the inventel kernel sources, and comparing with openwrt.
Perhaps other boards are afected, like Homehub 1 which is almost identical to livebox.
Could you give some clues or modifications to probe on this board?
any ideas are welcome
