Sorry for my Swenglish :)

We are using Gb- Ethernet and the backend servers delivers 2Gb/s to the clients.
I have two DL360:s with 2GB of memory each as lvs-machines.

I have deployed it at a customer sight which offers ftp,http and rsyc services.
They calculated that they will need 2^21 entries in the hash if it is supported.

Regards /Bernt

I'm not entirely sure if I understand this question? Do you want to know if 
increasing the hash table size is going to make a difference in lookup speed 
when 2Gbit/s of incoming valid traffic (means every packet matches a template 
entry) hits your director?

I would worry more about the amount of RAM you put into your box to be able to 
sustain this rate? May I ask if you plan on deploying it and if so, how is your
