I just tested on dxr2 (AM3352 based board) with latest mainline U-Boot. And the network performance is a bit better. But not as good as yours. Here my numbers:
Without this patch: ~400 KiB/s With this patch: ~570 KiB/s
Any ideas what might be missing on my platform? Why the speed is not as good?
I only got a small increase as well until I also grabbed the dcache enable patch. I need to find some time today to clean out the TI queue again.
Good point - indeed I had I/D caches enabled for other reasons already (md5/sha1 caclulations, ..)
Hmmm. I expected that caches are enabled already. Since I didn't see any "D-Cache disabled message" in the startup log.
If this is not that case, then such cache support would be greatly appreciated. :)
Check your logs? Unless you've also got a patched tree you should see "WARNING: Caches disabled" or so, because, yeah, oops, am335x got in with caches disabled, and then I forgot about it.
