You could try out the Dual Core Netplay experimental branch: https://dolphin-emu.org/download/list/dc-netplay/1/
It lets you use dual core in netplay games, works for the most part, might improve performance.
It is quite likely your connection causes a slow down though. When my internet experiences a slow patch, the FPS often drops from 60 to 20 until my ping goes down.
I play through Hamachi, but the ping is usually around 30, and peaks at 50, a direct connection is slightly better though.
