Memory swap usage 9.1GA and UTM220

Simon Shaw
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...

    Looks like that, far and away, is consuming the most RAM (~55%). The next highest is Snort for IPS, but that only accounts for 8%.
