gotcp

gotcp

A GO language TCP network library

Server example

1. Combining embed getcp.Session to create your own TCP network session

   For example:

    type Echo struct {
     gotcp. Session
   }
   
   func ( this * Echo ) OnRecv ( data [] byte , flag byte ) {
     if this . IsVerified () == false {
       // ...(业务代码，略)...
       this . Verify ()
     }
     // ...(业务代码，略)...
   }
   
   func ( this * Echo ) OnClose () {
     // ...(业务代码，略)...
   }

2. Register a network session class and enable services

   For example:

    s := & gotcp. Server {}
   s . RegisterSessType ( Echo {})
   s . Start ( ":3000" )

Client Example

1. Combining embed getcp.Session to create your own TCP network session

   For example:

    type Echo struct {
     gotcp. Session
   }
   
   func ( this * Echo ) OnRecv ( data [] byte , flag byte ) {
     if this . IsVerified () == false {
       // ...(业务代码，略)...
       this . Verify ()
     }
     // ...(业务代码，略)...
   }
   
   func ( this * Echo ) OnClose () {
     // ...(业务代码，略)...
   }

2. Connect to the server

   For example:

    echo := & Echo {}
   echo . Connect ( "localhost:3000" , echo )

Benchmarking

• Test code:

  • example/server/server.go
  • example/client/client.go

• Machine configuration: CPU 16 cores; main frequency 2600

• Number of processes: 1 server; 30 clients

• Startup script: test.sh

• 70% CPU of the whole machine

• Server program CPU accounts for 25.5% (407.9 / 1600)

• 23w qps
