If you are using a LocalDirector with a Cat6k switch, you can enable the Accelerated Server Load Balancing feature. This allows the Cat6k to forward the bulk of the flow (at wire speed), and lets the LD focus exclusively on the connection setup/teardown functions.

A friend of mine was using LD's on his service. They do
about 180mbps over
3 locations and were running performance problems. (They ended up moving to F5's). One of Exodus's Senior Network Engineers has seen
I heard rumor that Cisco was considering including LD capability in the 6509 MSN router module? that
become problematic at about the magic 80mbps you mentioned. I spoke with a few different neteng buddies when we started looking at LB's over a year ago and they all told me to stay away from the LD's. But like all of us,
get better as they stay around longer...
Probably, it's the same with all LB products ... you have to match the right products with your needs. Me, I have to go for the big scale. So I'll sacrifice features for ability to consistently handle the
consistenly they traffic and
scalability. I eliminated quite a few simply because they couldn't handle the volume, but that doesn't mean that they would work well for a site located in one of the big data centers.
