Performance is restored when the server is forced to 100MB FULL.

Primary servers are SLES 11 SP2/ZCM 11.2.3 on HP DL gear.

I can reproduce the same behaviour with SLES satellites using Dell
(Broadcom NIC) and HP (Intel NIC) desktops.

I created a Win7 satellite on one of the same Dell desktops and on
gigabit, it gave nearly the same performance as the servers when forced
to 100MB FULL, which is acceptable.

Thoughts? I really like to stick with Linux across the board for
