Port trunking

[Hive]

So i see lots of people who claim to be boosting host to host (Not multiple hosts to a single host) throughput/bandwidth by trunking ethernet ports. How exactly does this work?

Say if i have two Gb NIC's in two computers, both of them connected to a managed switch, does that mean i now have 2Gb/s throughput between the two computers?

If the teams are setup correctly on the hosts and the switch, then yes you should see a performance increase (this of course depends on the rest of the hardware in the two hosts).

Both are using 802.3ad aggregation, jumbo frames on (switch and server + other PC) RAMdrives on each, but the link never goes past 1Gbit/s

You need to check your load balancing method.

many methods will experience what you are seeing thou, 1gbit maximum because all the session characteristics are the same.

For example some devices allow load balancing on destination IP or destination port. In a single TCP session both these remain the same so they land on the same link.

If you do source IP and you transfer from different source PCs you can be lucky and 2 IPs land on seperate links or unlucky and they both land on the same link and both get 500mbit each.
