experian lock free

A recently maintained network server encountered performance problems, so it made major changes to the original program framework. Most of the changes are the thread working mode and data transmission mode. The final result is to change the lock usage mode. After some improvement, we can basically achieve GMB Network Adapter working at full speed. In After the performance was up to standard, I was wondering if I could use a more lightweight

One weeks ago, I wrote an article about the latch (latches) and spin lock (Spinlocks) in SQL Server. The 2 synchronization primitives (synchronization primitives) are used to protect shared data structures in SQL Server, such as pages in the cache pool (via a latch (latches)), and locks in the Lock Manager hash table (via a spin lock (Spinlock)). Next you will se

I assume that the bottleneck is in sync control, so I plan to add a fast single-threaded algorithm to the efficient,

popular non-blocking synchronization implementation solutions: Wait-freeWait-free means that any operation of any thread can end in a limited step without worrying about the execution speed of other threads. Wait-free is based on per-thread and can be considered starvation-free. Unfortunately, this is not the case. The use of wait-

, a variety of scenarios (1P + 1c,1p + C, multi-p + 1C), and a variety of message processing methods that are worthy of a good thing for us to learn. Especially in single-producer or single-consumer mode, it can be simplified, which we have not considered, and here is not considered, we still have a multi-producer + multi-consumer model to discuss, because the single producer or single consumer mode is relatively simple.Disruptor in a single producer + single consumer (1 producer + 1 Comsumer),

Lock free (Chinese characters are generally referred to as "no lock" and generally refer to the CAS instruction-based lock-free technology) is to use some special atomic commands of the processor to avoid lock in traditional paral
