Hi Dragon,
How did you solve your SoftIRQ problem? I have same problem. I need some help.

Thanks,

SUMMARY OF OPTIONS FOR CROSSBEAM PERFORMANCE IMPROVEMENTS

On both platforms: C25 and X80:

• make sure that SecureXL is turned ON
• if majority of traffic is HTTP, modify default object settings: in object properties, go to Advanced service properties in SmartDashboard and change Protocol type to "NONE"
• turn off Sync in Cluster and logging for any non-critical sercives, for example HTTP
• use sim affinity command to hardcode interface allocation to a specific CPU (details in this thread) *** new update - do for both not just C25 ***

For C25 / COS:

• make sure that you are running R65 HFA02 or else you might experience packet drops on interface, check with netstat -i
  

For X80 / XOS

• if NATing is used, make sure that reclassify-nat-flows is switched on
• if you use VLAN tagging, make sure that hide-vlan-header is set on each tagged interface

Combination of these helped to reduce CPU load by approx 50%.

REMEMBER: With SecureXL switched ON tcpdump and fw monitor outputs won't be "correct" *** new update - works fine with R65 and above ***
