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

In very brief terms:

  • CoreXL: Technology that makes use of multiple processor cores
  • SecureXL: Connection acceleration technology (both throughput and connection establishment)

The linked information other people have provided have more detailed information.

Can we get more info on what secure XL does vis hardware offload on 'other' routers and their network devices?
Also, why would secure xl (if this is what does it) rewrite network traffic?  I have had issue after issue with secure xl causing issues with mgcp and sip traffic.     Disabling secure xl resolves the issue.  However, CP Engineers are not able to provide me guidance other than "you need to look at this or that 'sk' and update to the latest 'take'."

Version R80.10 or R80.20+ in regards to SecureXL?  It makes a big difference...
