Hi - Just upgraded from 2862ac to 2865ax. Used 2862 cfg file and imported into 2865ax and it works fine.

But I notice that 2862 ran at 59% memory usage and 2865ax runs at 90% although cpu usage on 2865 is 2%

Early days (just upgraded today) so no evidence of any issues.
Did upgrade to latest reset firmware to clear 2865 totally, then imported 2862 cfg file.

Just at a loss why same cfg which is not that complicated uses 90% memory.

How can I tell what is using the memory.

Thanks for any advice.

What memory does your 2865ax use?
 

Mine is always at 88-90% with CPU <10%. That's with a pretty basic home use setup - two LANs, one VPN, low throughput. I can't see a way to look at how the memory is used.

Thanks...good to know its as expected.

2865ax works fine so far so good...

Unless we both have misconfigured or malfunctioning devices! It does seeem odd that 90% is used when doing almost nothing - it doesn't leave much headroom, but perhaps memory use doesn't scale with work (i.e. it's already precallocated RAM for everything it could be asked to do).
