Any performance gain from 19.1 to 21.7 version?

[labsy]

Hi,

I have production on 19.1 version on this:
- Host is FUJITSU server on ESX 6.7.0 Update 2
- OPNSense is 19.1 with approx. 4000 active states on average
- it has some 40 NAT rules
- it also has quite large BLOCKLISTS on FW Aliases (loading external files of up to 4000 IP addresses to block
- WAN is 1 Gbps bandwidth in datacenter

What do you think - will I gain or loose performance wise if I upgrade to 21.7?
It is PITA, because I will "upgrade manually", meaninig I need to rewrite by hand all rules and settings. Auto upgrade is not possible.

You will loose a bit performance in theory since 20.7 switched to FreeBSD 12, but for 1GB thoughput not measureable. You mean 4000 active sessions? Thats no really a lot when handling via good CPU.
Why is a auto update not possible? About 6 months ago I updated an old 19.7 machine, should be possible.

Thank you.

Well, I have VMWare 6.7 u 1, so it's virtualized HW. With mentioned 4000 active handles it's scratching the floor, not spiking over 8% CPU, so I guess performance wise would be fine.

Regarding UPDATE....I guess breaking point is 19.1 --> 19.7, because 19.1 was the last possible auto upgrade. From there on traffic was stuck, I tried twice, spent whole day trying to upgrade 19.1 to different versions, even one step up, but at no avail.
So I am stuck with 19.1 and need to manually upgrade.
