本文通过测试Proactor模型在Windows、Linux及Solaris平台上的表现，对比了不同操作系统下文件传输的效果。发现Windows平台能顺利完成文件传输并正确写入数据，而Linux和Solaris平台虽然能够接收数据但在文件写入方面存在问题。

1、什么是ACE（略）

2、什么是Proactor（略）

3、例子：/ACE_wrappers/examples/Reactor/Proactor/test_proactor

3.1、运行环境

172.16.34.11：winxp

172.16.33.34：linux（版本略）

Output为0，文件没写入：(

3.4、33.34作为服务器端（略，因为不支持）

4、结论（仅根据现象）

Windows对proactor支持得不错，起码走完了流程，成功接收从linux发来的文件，并新建文件写入数据；solaris从屏显上看也异步接收了数据，创建了文件，但没写入（不知原因），最令人费解的是客户端发送几次后ACE_POSIX_AIOCB_Proactor::delete_result_aiocb_list

number pending AIO=0，由此终止，再连：ACE_SOCK_Connector::connect: 由于目标机器积极拒绝，无法连接；linux不支持，作为服务器无反应。

5、应用背景

之前有个用proactor框架做的并发服务器已在windows上作为服务运行得不错，现想移植到linux或solaris上，框架不变，仍用proactor。但从基本例程的运行来看，似乎还需进一步分析可行性，也期冀技术上被支持，资源难寻呀！找了个ace的qq群，几十人尚无人帮助我，期待！
