Hi,
We have a performance issue with our ASG installed on a test computer. I know that Astaro run best on dedicated appliance, but i should work fast enought on a standard PC.
The problem is that when a few users (2-3 are enought) try to access internet at the same times, it become so slow that web site can't be displayed.
I notice that when swap sapce is not use performance are quite good, but as soon as Astaro use the Swap, it slow down. I did some ping test through the firewall, and they were OK (avg 170 ms for www.google.com), so i set http proxy inactive, but it doesn't change anything.
The HDD is a standard IDE 7200tr/m hard drive. The avg used RAM is 63% of 495 Mb. And CPU is about 1-2%.
Any advise on how to solve the issue?

Hi,
Thanks for all your info.
Plan was made to upgrade the server, but the NIC is not detected on the new server (Dell T105 with dualcore opteron and 1Gb DRR2) so we stay on this one for now.
Feature used : SMTP and POP3 proxy for anti-spam with end user portal to manage the quarantaine.
There is 3 DNAT Rules (OWA, POP3 and sharepoint access) and one masquerading rule (for internet access)
Intrusion detection and Remote access is also unable.
We have 5-6 internal (internet access) user and 40 outside user (OWA and sharepoint access)
Regards,

Like everyone else has said, RAM could be a huge issue, but check to see if you're running the anti-virus scanner on your web proxy, that will bring Astaro to a stand still like you describe if a number of users are online. You may also want to make sure that if any computers are auto updating software like google, adobe etc that they are in your exceptions list. Not the computers but the destinations. I found that to be my CPU hog, I couldn't get two people browsing at home without having it come to a stand still...
