Fly VMs specs

[kevin11]

Hi!
Would like to understand more deeply the specs on fly vms.

I’m running a shared - vm - free plan and i’m thikning on upgrading for more memory/dedicated performance.

I have a couple of questions.

1. Other than memory, what is the main advantage of going to a performance-cpu vs a shared-cpu?
2. What are the specs of these machines/cpus? like, intel processor?
3. In general what should one be looking for when going over from shared to performance cpu (other than memory which I understand more than the CPU allocations)

1. Shared CPUs can have up to 16 other people using the CPU at the same time. This is great for apps that don’t use much CPU at all. When you try and sustain CPU usage on these, however, you will get throttled. Performance CPUs will generally get full access to a CPU.
2. The actual hardware is virtualized out, but here’s what lscpu returns:

Architecture:                    x86_64
CPU op-mode(s):                  32-bit, 64-bit
Byte Order:                      Little Endian
Address sizes:                   48 bits physical, 48 bits virtual
CPU(s):                          2
On-line CPU(s) list:             0,1
Thread(s) per core:              1
Core(s) per socket:              2
Socket(s):                       1
NUMA node(s):                    1
Vendor ID:                       AuthenticAMD
CPU family:                      25
Model:                           1
Model name:                      AMD EPYC
Stepping:                        1
CPU MHz:                         2595.124
BogoMIPS:                        5190.24
Virtualization:                  AMD-V
Hypervisor vendor:               KVM
Virtualization type:             full

This is for a performance-2x machine I have running.
3. Just better performance for CPU heavy applications in general.

We use a variety of CPU models across our workers - mostly AMD but some Intel as well.
