What datacenter are you collocating this in if you're able to provide unlimited transfer? Are your VM's given the gigabit connection or just a fraction of it. Most providers just make the speed slow to make it unlimited bandwidth, tried Vultr before and I must say it has the slowest speed ever of VPSes I've utilized, my own and rented for storage/GRE/CDN purposes.
