A typical Node.js application often has 10,000s to 100,000s of live objects. A major garbage collection cycle normally completes in under 10 milliseconds. (In practice, most will be minor scavenges that complete in < .1 ms.) -- -- v8-users mailing list v8-users@googlegroups.com http://groups.google.com/group/v8-users --- You received this message because you are subscribed to the Google Groups "v8-users" group.
