2014-06-01Improve XPath allocator performanceArseny Kapoulkine
When allocating new pages, make sure that the page has at least 1/4 of the base page size free. This makes sure that we can do small allocations after big allocations (i.e. huge node lists) without doing a heap alloc. This is important because XPath stack code always reclaims extra pages after evaluating sub-expressions, so allocating a small chunk of memory and then rolling the state back is a common case (filtering a node list using a predicate usually does this). A better solution involves smarter allocation rollback strategy, but the implemented solution is simple and practical. git-svn-id: https://pugixml.googlecode.com/svn/trunk@999 99668b35-9821-0410-8761-19e4c4f06640
