TCMalloc, a malloc developed by Google,[31] has garbage-collection for local storage of dead threads. The TCMalloc is considered to be more than twice as fast as glibc's ptmalloc for multithreaded...TCMalloc is a malloc replacement library optimized for multi-threaded usage. It also features a built-in heap debugger and profiler. It also features a built-in heap debugger and profiler. To build MariaDB 5.5 with TCMalloc , you need to use the following command

Various solutions to this have been proposed for BEAM, such as switching from a shared-nothing heap to a shared heap or a hybrid heap (where message-passed objects are copied once), however the Erlang garbage collector is not suitable for managing shared/hybrid heaps and would need to be rewritten for the task, and nobody has managed to get the shared/hybrid heaps working with Erlang's SMP ...

Jan 10, 2008 · From memory, xdelta patches only contain copy and insert instructions. They might contain very small amounts of context for changes under the minimum match length, but the patch file is binary and the context is quite small, so it might still be safe. pd Says: January 11th, 2008 at 6:03 am. Ben what is the conclusion to your story?
In this case the chain b->c is in the critical path (a can be in parallel with b, and the sub has minimal latency); the store is not in the critical path. So as you can see there is an additional dereference. Also it will touch the additional cacheline pointed by data+sz.

jemalloc recognizes that minimal page utilization is no longer the most critical feature. Instead it focuses on enhanced performance in retrieving data from the RAM. Based on the principle of locality which states that items that are allocated together are also used together, jemalloc tries to situate allocations contiguously in memory. -
tcmalloc achieves its speed by never returning memory to the system - free space reclamation is one of the slowest parts of any allocator.

Oct 25, 2016 · For those of you who are coders, a base image is a little like an abstract class. It defines some important characteristics that are meant to be re-used, but it leaves others to be resolved later. The Docker community already provides a set of base images like the Fedora:20 image which have been hand-crafted to provide a minimal OS.
