I have a problem with the Ironport S-370 in one of the sites, everything is working fine as the customer needs but there is (30 seconds) of delay when the users try to access any non-cached website. I contacted Cisco Ironport support, they checked the server and they told me that everything is fine but they recommended using a public DNS in the DNS settings instead of the local DNS. I have done it but unfortunately, the problem is not solved.
And it is worth to tell that:
- When they use the old proxy server (ISA server 2003), they can access the cached and non-cached websites with no delay.
- They have 500 users and they are planning to make them 800 users in the end of the month.
- The RAM utility is showing more than 80%, CPU utility is showing 10% (but the cisco support team think that is normal).
