[Bug 33365] New: Poor performance of memory allocator
http://bugs.winehq.org/show_bug.cgi?id=33365 Bug #: 33365 Summary: Poor performance of memory allocator Product: Wine Version: unspecified Platform: x86 OS/Version: Linux Status: UNCONFIRMED Severity: major Priority: P2 Component: ntdll AssignedTo: wine-bugs(a)winehq.org ReportedBy: alexpigna.dev(a)gmail.com Classification: Unclassified If there are many blocks of the same size in one of the free lists and a slightly larger block which falls into the same free list is allocated the list will be linearly scanned for a suitable block, potentially blocking for a very long time. This situation actually happens in the game Deponia, under certain conditions. A possible solution would be to round up all allocated blocks in a size category to the maximum size of the category. In this way the allocator could always get the first block from a free list. This would waste some bytes, for each allocation, but avoid the linear search. This solution would be similar to how the jemalloc allocator works AFAIK. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

Is this still an issue in current (1.7.37 or newer) wine? If so, please attach the terminal output in 1.7.37 (see http://wiki.winehq.org/FAQ#get_log). -- Do not reply to this email, post in Bugzilla using the above URL to reply.
