Hi David,

After upgrading to 7.2 (amd64) some customers complained of very poor
bandwidth. Upon investigation all the effected customers were ATT DSL
clients located all over the USA, not in a single city, nor were other
ISPs effected. The server is a Supermicro with dual (quad core)
processors with a single Intel fxp network card on a 100mbit connection.
Could you please try if this would help:
sysctl net.inet.tcp.tso=0
Cheers,

Thank you! This hint has saved me a lot of troubleshooting.
I was having the same issue as David with 3 servers recently upgraded to
7.2. Clients (MS Windows) were complaining that they were having
intermittent connectivity issues talking to these servers (https, imaps).
They too have fxp network interface cards, no issues with other servers
upgraded to 7.2 with em cards.
Thanks again.
Regards,
Nigel.
