Re: FG-60e vs FG-60f
Memory size has the most impact on the number of concurrent sessions. And, as far as I know, both models feature 2 GB of RAM. A faster CPU accelerates the rate of new sessions (although not much, according to the datasheets), but has no negative impact on any performance figure that I know of. Look at the throughput figures for AV, IPS, threat protection, they are up by a factor of 3 - this is not due to higher CPU performance but the new generation of ASICS/SPs.
If you really consider putting so many sessions on a tiny box like this, even only 50% of the datasheet maximum figure, you are ill advised IMHO. These 60s are fanless desktop boxes, good for a couple of 10.000 sessions but anything beyond asks for a 3-figure-FGT (100F and above).
First model with more than 2 GB is the 80F. The datasheet figures do not reflect this unambiguosly, though. You will notice in memory usage while it's running.
