A few years back a terrific Kerio support rep made a hardware spec suggestion for me. I'm curious to know if that same advice still stands.

He said that clock speed is more important than the number of cores. Is that still the case?

What about Pentium vrs. Core i7?

Based on our experience following specs should be sufficient for 100+ users and 250+ connections:

Intel Core i3 (we have only systems with 5. generation or newer)
8GB RAM
128GB SSD (or smaller if you do not use proxy cache)
Intel E100 or I350 Network card with offloading features

One connection can only use one core, so if you have many users or parallel connections 4 cores or more makes sense.

When speaking of high bandwidth connections (500mbps+) and you want to reach this speed with one download, the clock speed is crucial. We get around 400mbps with a core-i3 6100.

Hi

Speed is important however we also suggest having a minimum of 4 cores. This depends highly on the number of simultaneous downloads and the number of clients connected of course.

For 100+ users I would suggest an i5.

You can cross-relate the hardware specs of the Kerio Control hardware appliances vs the maximum number of users here:

an NG500 is suggested for 200 users and it's an i5

I had opened a support ticket some weeks ago because we were not sure if the NG500 is suitable for a customer with 200 clients.

At the end they suggested to use a virtual appliance or custom hardware because of the 4GB of RAM.
They also mentioned that one could change the memory with a bigger one, but then the warranty is not valid anymore.

In our experience, this amount is only sufficient for very small businesses (<30 Clients).
