If the answer is 'yes' to the previous question, instead of removing the comment from maxPacketSize, do you see a similar performance benefit if you add a new field later in the structure? Perhaps after 'refCount' or 'securityIndex'? As Simon said, if there is a problem with how this structure is being processed, we probably have a similar problem throughout the code base. It is important for us to understand what the cause of the problem is.
