Re: MSI X58 Platinum I7 920 with onboard everything
It is not an unlikely scenario that one of the revisions of the 8111C chip has some problems with the driver (There are 5 revisions total of C and CP versions).
It is also not unlikely that there may be a combination of Client OS, configuration and hardware that is having problems (for example with jumbo frames), after all this is very much use at your own risk, or it may just be faulty hardware.
However I can say that using Ubuntu Hardy server - amd64 as a client OS and after sending 100s of GB through the network with it shows no degradation
on the r8168 NIC. On the other hand the realtek drivers all are CPU bound and may have some problems if the CPU is maxing out, but I have not seen any problems like this although performance do drop off while the CPU is loaded hard (but recovers again).
PS! I do not have one of those MSI X58 Platinum I7 920 and a Windows server 2008 but if you (or someone else) will send me one I will be happy to test it and make the ESXi driver work (if possible)
