HP ProBook Installer 6.1 (beta): Ivy bridge support
The performance problem is only with SMB and only with Mieze's kext. With slice's and lnx2mac I get acceptable performance to the same SMB share. And with Mieze's kext I get excellent performance from an AFP share. So it is a problem isolated to SMB+Mieze code. A sort of timing problem or a bug in the kext that only manifests itself with SMB.
I've read your conversation, but I don't think the LAN kext is the problem, at least not the whole problem. I'm also getting slow speeds (around 2-3 MB/s) when I try to copy files from/to my NAS (Zyxel NSA-310 running Linux-based firmware) via SMB and this is on WiFi link. Recently I enabled the build-in NFS feature and now I can transfer files from/to with the maximum speed, which my router (TP-Link TL-WR1043ND, running OpenWRT 12.09 Final) allows me to use, which is around 8.5-9 MB/s (this is on my desktop with Atheros 9280 WiFi card, on my ProBook the speed is around 5-5.5 MB/s). Maybe Mieze is right about the Apple's SMB implementation, which indeed seem to be fundamentally flawed.
