If you're ever in Northern VA hit me up cause I owe you a beer in a big way. We've been struggling for a while with our coldfusion performance problems and to gain the knowledge and come up with this solution would have taken us a loooong time. It worked just as you described. Many thanks! Wow. If you’re ever in Northern VA hit me up cause I owe you a beer in a big way.

We typically use a 1GB min and max. This helps against the effects of heap fragmentation (better ensuring the Young Generation Guarantee) and prevents the Full GCs that must be run when the heap is automagically resized.

However, I have one question. What is the proportion of the above settings to the overall memory allocation? That is, what is the -Xmx setting? Do you make the Eden space a certain percentage of the overall allocation? Great read! However, I have one question. What is the proportion of the above settings to the overall memory allocation?
