I'm trying to understand CoreXL and SecureXL.
1. What is CoreXL and SecureXL ?
2. Why are we using coreXL and SecureXL ? What are the use of those ?
It's not a topic you can cover here. But both provide means of improving firewall performance. SecureXL will accelerate packets from interface to interface for known traffic thus saving CPU usage and CoreXL adds ability to run multiple inspection cores concurrently. But that's very high level.
Probably the best is to read this SK "Best Practices - Security Gateway Performance" sk98348
you should definitely buy Tim Hall Max Power book for having a better understanding of this two concepts related to firewall performance optimization , then there is atrg on the support center that can explain in deep those mechanism but with Tim book you can have real life implementations well explained
How about RTFM first?
