Jiangyi Liu has been working on mbuf limiting code for the past week or so. What he has is pretty complete, I expect to get most of it committed once Bosko gets back. <lots of other things deleted> There are tons of nice ideas presented here, but I'm going to have to side with Terry on this: SLOW DOWN! Socket scaling is good, but before it can be discussed seriously, the code has to be written and it has to be tested. Once Matt finishes his code (or someone beats him to similar code), it can be tested and the discussions can continue. As for the whole thread on mbuf allocation and exhaustion: Please end it, it's a diversion from the topic at hand, which is improving performance.
