Synology Multipath SMB, and iSCSI
So... normally when you want faster networking, you can just upgrade to faster NICs (10g, 25, 40, 50, 100g.. etc...).
However, in the case of my Synology DS423+, you get, two 1G ethernet ports with no expansion.
You would think the best course of action, would be to leverage LACP- however that is NOT the case.
Enabling Multichannel can double the amount of bandwidth per client, where as LACP, depending on hashing, only gives benefit up to the performance of one port.
This post details how to enable multipath for SMB, and how to configure iSCSI on linux with multiple paths.
