errr.... you said above that Contabo vps connection speed is 200Gbps. I think thats an error.

Thanks for picking up on it.  @Manalet me know too.  I wrote the post in the early morning hours, and just at the time when I got into bed it flashed through my mind I could have done that.  So now I know I did.  I've fixed it now.  It's 200Mbps.

OpenVZ is easy to spot in most cases:

I'm sure it must be.  I'm almost certain you'd have picked it up immediately from just reading through the specs at Cantabo.  I'm a bit of a dumb dumb with it.  I need to have it written in black and white, and for the life of me can't understand why Contabo doesn't make a big deal out of KVM - they're more enthusiastic about 100% SSD.  Like for me that's a really great promo point to push.

the kernel is always 2.6 because openvz host must run a modified 2.6 kernel that is shared with the guest . the kernel version is most easiest way to determine since most newer distro already use kernel 3 or 4 . Openvz also cannot use latest distro like ubuntu 18.04 if you try it it will brick the openvz vps because of incompatibility with the old 2.6 kernel . If openvz did not try to upgrade their kernel soon enough it will be lesa of an option from time to time due to much more package not having support for old 2,6 kernel

Aha - now that I'd be able to pick up on with the benchmark test. Or to do the CAT command. I won't forget 2.6 now, thanks for pointing that out @humanpuff69.
