Memory swap usage 9.1GA and UTM220

We have a UTM220 device, upgraded to 9.1 yesterday.

40 devices/users protected.
Network Visibility, POP3 Proxy, RED, Endpoint Protection, WAF and HA are all OFF.
HTTP Proxy web caching is off.
IPS is using only 7980 of 15806 patterns.

75-300 users are recommended by Sophos for this unit type.

However memory swap climbed almost instantly to over 50% of RAM. I know there has been some discussion on swap usage, but am unsure of the outcome. CPU looks fine.

Can someone send me a summary of Sophos comments on swap/memory usage as I'd really not like to throw 100-200 users on this device...

according your graph it looks like you rebooted at 8:45... prior to that i see that the usage was around 50% already?

Perhaps its always been about 50%?

Its not officially supported/recommend but the UTM 220 rev5 can support 4gb of ram...maybe go buy some ram. If I remember correctly it comes with 2 x 1gb ddr3 sticks (not sure on speed - taking the old ones out will show you)

We have upgraded our ram to 4gb (2 x 2gb sticks) and we haven't had any high swap usage at all 7% swap and 40% mem usage.
