Connection rate is most effected by the number of CPU cores configured to run secureXL.
Today it is recommend to us up to 6 cores for secureXL. Beyond that it becomes inefficient as locking mechanisms take their toll.
R80.20 is being developed to enable greater scalability and modularity in software, required to utilize the new acceleration cards and other technologies down the road. It will deliver a significant increase in connection rate for Security Gateway Appliances that have enough cores to benefit from this enhancement.
