it implements all of these tasks on the client side (User-space) with better resource and time management. The disadvantage of this model is that, on multicore systems, these programs often have poor extensibility.

: This article mainly introduces (summary) the advantages and disadvantages of NginxLVSHAProxy server load balancer software. For more information about PHP tutorials, see. PS: Nginx/LVS/HAProxy is currently the most widely used three load balancing software. I have implemented these software in multiple projects. I have referenced some materials and combined some of my experience in using it, to sum up. Generally, server load balancer uses different
