We have been running our ClearOS v5.2 as a standalone proxy, with content filter for some time. Total user count 55 with at best 50% online at any given time.
It is running single network card and access to the Internet is via a CheckPoint firewall, users have started complaining about poor performance and the web in general being sluggish. This has been tested by us in Tech Support and we agree.
The LAN is split in two by a layer 3 CISCO 6509, with Plant based systems being 10.10.0.* and servers 10.10.4.*. The proxy is on the 10.10.0 side and the main Checkpoint firewall is on the 10.10.4.0 side. The route out of the building is through the CheckPoint and then onto a BT 2-Wire router.
As a control test we have built a second COS 5.2 system, but this time in gateway mode with its second interface connected to the other side of our LAN. This is equally poor in page load times despite being a better spec'd system. When we connect the external interface of the test system direct onto the 2-Wire router then everything is quicker.
If at all possible we want to avoid converting our existing standalone into gateway mode.
Can anyone shed any light as to why we are seeing the performance issues?
