Webcompaction_alloc() isolates free pages to be used as migration targets. While its scanning, IRQs are disabled on the mistaken assumption the scanning should be short. Analysis showed that IRQs were in fact being disabled for substantial time. A simple test was run using large anonymous mappings with When a garbage collection is triggered, the GC traces through the live objects and compacts them. But because compaction is expensive, the GC sweeps the LOH; it makes a free list out of dead objects that can be reused later to satisfy large object allocation requests. Adjacent dead objects are made into one free … See more If an object is greater than or equal to 85,000 bytes in size, it's considered a large object. This number was determined by performance tuning.
