How to configure session time on ASA 5500 series
The packet inspection done by the ASA does take some time, and does delay the packets. You could try putting it back in, and then remove the ‘inspect’ commands one by one, and see which one is causing the most problem, probably the http inspection. Also you may have configured Java inspection or blocking, this [...]

How do I use my 2 CISCO ASA 5520 with my CISCO 2800 Router over my LAN
I presume this is some sort of lab exercise ? Otherwise this is not the sort of setup I would expect in a datacentre. If you have two ASA5520, then configure them as a failover pair, and use the management lan interfaces as the failover link, as this is much quicker, and keeps session information, [...]

Can an IPS collect information of all layers like like which protocol and port numbers are being used or it can only sniff till layer 3 detail ?
The IPS should be able to see above layer 3. Layer 4 is where the session information resides – so it could tell the difference between UDP & TCP for example. It should be state-aware like a firewall.

Browser associated with shortcut?
Yes, try this: - Do not create an “internet shortcut”, but a normal shortcut with the target pointing to the browser you want to use (for example “C:Program FilesInternet Exploreriexplore.exe”), and then append the URL at the end of that target. So, the shortcut’s target should look like this: <pre> “C:Program FilesInternet Exploreriexplore.exe” http://www.itknowledgeexchange.com</pre>
