redis lua performance

A simple Python script that monitors Redis performance has already talked about how to monitor memcached, and now incidentally how to monitor Redis. Let's start with the following information about monitoring redis: Redis Ping: Verify Ping

default use of the configuration file, you can see the configuration of alpha, beta, gamma, Delta, Omega Five connection pools as an example. We only retain Alphaand configure two Redis servers with ports 6379 and 6479. After that, two Redis instances are configured and started accordingly. You can start twemproxy now, and you can run the src/nutcracker directly. Test if it's connected. Connect to the twem

Redis and memcache do not have much difference in write performance, read performance above especially bulk read performance above Memcache fully wins, of course, Redis also has its own advantages: such as data persistence, support more structure (Set List zset), etc.Redis a

structure, Tomcat and Ehcache can be deployed on the same machine.The test results based on this pattern are as follows:The QPS can reach around 1.3w , and the performance bottleneck is the poor performance of Tomcat over Apache and Nginx processing requests on Tomcat processing HTTP connections.Advantages: The business logic and storage server are developed in Java, which is good for maintenance and can s

was down, the Slave of the backup was cut into the Master machine, but this scheduled task was forgotten to be deleted, which led to the above tragedy, the reason was found only a few days later. Setting the no-appendfsync-on-rewrite configuration to yes can alleviate this problem. Setting it to yes indicates that the new write operation is not fsync during rewrite and is temporarily in memory, wait until the rewrite is complete before writing. It is best not to enable the AOF backup function
