1.2-RC1 High Processor Utilization

[fastcon68]

We have been using PF-Sense for a couple of months now.  We have just recently upgrade from Beta 2 to RC1. 
We have the following things going on and I don't know where to start trying to fix them.

1.  High Processor utilization - We have noticed processor utilization of 50% constantly.
    We are running the following modules on top of RC1
          1. Snort
          2. Dashboard
          3.  ntop
          4.  IPSEC VPN
          5.  SNMP
          6.  DNSmasq
          7.  DHCP

2.  3 wireless clients - that are all loosing connection then reconnecting.  All three have different wireless clients.

3.  Getting web server to work from with in the internal lan to the WWW.

Does anyone have any thoughts?

Here is some additional information:  I am using a Dell 440 SC for the firewall.  I have a Dell 10/100 adapter and a Dell Broadcomm 10/100/1000 adapter on the internal network.  I have a dell 8 port GB switch connected to a Linksys 4 port wireless router.  The linksys is a model 1 and has the current version of the firmware on it.

I have a clone workstation. a Dell 380, and Vostro 1500. All three have wireless and they are online

NTop is causing your issues.

[fastcon68]

I will try to turn it off and see how that goes.  It does not seem to be brothering preformance, except for the management console.

Overall the product is dynamite.  it seems to be much stronger that M0n0Wall.  I use both and they both have their place.

Turned off ntop ( :( ) and it seems to running at about 1% on the DualCore 3.0 Ghz machine.  I have not run into any issues so far.  I wish we could limit ntop resources so that it did not hog the processor so much.  ie capture data every (5, 10, 30, 60)  on a time basis.

NTOP has a long history of hogging the CPU unfortunately.
