高并發C++應用程序框架：saf application framework

saf (saf application framework) 是一個高并發的c++應用程序框架，它以RPC為基礎，提供了動態載入模塊的特性，為服務端開發人員只用關注于程序的業務邏輯，就可以實現遠程方法調用，而不會關心底層的通信細節，另外，它還內置了一個簡單的http server，用來查看服務器的運行狀態。

特點

1:基于 google protobuf 的 RPC 框架
2:內置簡單的http server用于查看系統狀態
3:模塊化的管理,只用在lib中增加動態庫就可以達到增加rpc service的目的

編譯例子

1:下載源碼,它依賴與sails公共庫:

git clone --recursive https://github.com/sails/saf.git

2:執行編輯腳本:

./build.sh

3:編譯測試樣例:

cd example
./build_test.sh

4:運行測試,比如運行echo_sync:

./src/server
./example/echo_sync/client

5:增加子模塊,配置conf/sails.json: 在modules里增加一行,name是子模塊名,path是子模塊動態庫的路徑

性能

測試一

筆記本: T6400 @ 2.00GHz, cpu num:1, cpu cores:2 服務端和客戶端都運行在這臺電腦上

| server handle threads | client call threads | earch threads call num | run time  |
|-----------------------+---------------------+------------------------+-----------|
|                     1 |                   1 |                 100000 | 0m14.674s |
|                     1 |                   5 |                 100000 | 0m30.896s |
|                     1 |                  10 |                 100000 | 1m0.848s  |
|                     2 |                   1 |                 100000 | 0m14.409s |
|                     2 |                   5 |                 100000 | 0m27.911s |
|                     2 |                  10 |                 100000 | 0m50.760s |

2w tps.因為客戶端和服務器在同一臺電腦上,所以測試結果會比實際更低.

統計

內置http服務器的默認綁定在端口8001上,所以可以通過輸入localhost:8001/stat來查看統計信息:
