, no replication, asynchronous mode, message payload 100 bytesTest Project: Cluster total throughput rate for 1 to 3 consumer respectivelyTest result: With a large number of messages in the cluster, the total cluster throughput when using 1 to 3 consumer as shown inIt is known that a single consumer can consume 3.06 million messages per second, which is much larger than the number of messages a single producer can consume per second, which ensures that messages can be processed in a reasonable c

Ruilog Agian for his work of second benchmark of YAF 2.1. YAF 2.1 (Docs) did a lot of work to improve performance and reduce memory usage, so let's take a look at the result (Yaf 2. 1 rewrite a lot of logic to improve performance, and reduce memory usage, improve results see test comparison): The "All", I have to say, I am isn't saying the fastest is the best.

2017 Golang, Python, PHP, C + +, C, Java, Nodejs performance comparisonI in Php/c++/go/py, whim, want to make a simple comparison of the recent mainstream programming language performance, as to how to compare, still have to use the Magic Fibonacci algorithm.

Recently learning Golang, always want to experience the next concurrency in the end have more, will I big python strong how much. Learned the official tutorial HTTP service, using the Performance test Tool WRK test, found the result is very surprising ~WRK can refer to my blog, there are basic usage notes: http://blog.yuanzhaoyi.cn/2018/01/12/test.htmlTest command: wrk-t10-d1m-c200 http://127.0.0.1:8080Mean

true that, as you might think, there will be at least one more boost to using Jsoniter performance? The answer is not necessarily! After our pprof analysis, we replace the JSON library with the following image: In terms of time, serialization took 9.3s, which was intolerable at this time. Then, out of doubt, I have the call stack diagram of the original JSON Formater, as follows: The result is very magical, the original Encoding/json to hit th

This is a creation in Article, where the information may have evolved or changed. Golang in the GC this block is relatively weak, frequent application and release of memory will consume a lot of resources. In addition, slice uses an array implementation, there is a problem of capacity and length, when the capacity of slice to continue to add elements need to expand, and this expansion will apply for new space, the old content copied into the new space

: Advantage of using NULLS over Empty Strings or zeros: 1 NULL requires 1 byte 1 Empty String requires 1 byte (assuming VARCHAR) 1 Zero requires 4 bytes (assuming INT) You start to see the savings here: 8 NULLs require 1 byte 8 Empty Strings require 8 bytes 8 Zeros Require bytes On the other hand, I suggest using NULLs over empty strings or zeros, because they ' re more organized, portable, and Requir e less space.
