[rhn-users] vsftpd performance very slow

[dbossung at southeast.edu]

David,

I think I am experiencing some of those 'know issues' you speak of. After
emailing Daryl, the nic has oscelleted between FD and HD on a very random
basis. Just all of a sudden, for no reason, the duplex will change.

I have already taken your advice and switched nics. All is well with the
new Intel.

Damn Micron for using a motherboard with this chipset, been nothing but
trouble since we got the clientpros. :(

Thanks for your input.

Don

It's worth noting that there are known issues with early generation
Yukon MAC and PHY chips including auto-negotiation.  Check with your NIC
vendor for details or try a different NIC (Intel, etc.)
