Modify the source code

The parameters of Aria2 -max-server-connectionlargely -min-split-filesdetermine the download speed of the network disk.
Here I -max-server-connectionset the highest to 256 and -min-split-filesthe smallest to 256k.

    #aira2的基本配置选项大多都存储在文件OptionHandlerFactory.cc中
    vi src/OptionHandlerFactory.cc

    #定位到441行
    #将服务器最大连接数16修改为256
    OptionHandler* op(new NumberOptionHandler(PREF_MAX_CONNECTION_PER_SERVER,
                                              TEXT_MAX_CONNECTION_PER_SERVER,
                                           // "1", 1, 16, 'x'));
                                              "1", 1, 256, 'x'));
    #定位到第503行
    #将最文件分片大小设置为256_k
    #到此源代码需要修改的地方改完了
    OptionHandler* op(new UnitNumberOptionHandler(
    //PREF_MIN_SPLIT_SIZE, TEXT_MIN_SPLIT_SIZE, "1M", 1_m, 1_g, 'k'));
     PREF_MIN_SPLIT_SIZE, TEXT_MIN_SPLIT_SIZE, "1M", 256_k, 1_g, 'k'));
