Problem is, web apps that require low-latency realtime requirements are not that uncommon. Think about anything related to trading or bidding. Of course, if the plans are to be believed, then a guarantee that the GC doesn't exceed X ms is good for soft real-time requirements, which is often enough. > The one outlier report I mentioned was of GC randomly stopping processing for several minutes, which clearly isn't within the bounds of acceptable response time for web apps That's not acceptable for any kind of app and the problem gets bigger the more heap memory you have. The sweat spot for GC enabled apps seems to be 4 GB - anything bigger than that and one should prepare for surprises.
