[求助]write系统调用性能下降5倍，可能是因为什么导致。

adamzyg · 2024-09-26 21:15:42

首先申明一下，这个系统不是archlinux，我不知道应该发到哪个主题下。
我这个是Xilinx的SOC，我们编译的两个运行的版本内核版本完全一样，我用strace跟踪了一下trace=write这个系统调用，发现两个版本的write系统调用性能相差5倍。
因为是客户的程序，出现性能很大变化，所以提出这个问题。这里write写的应该是socket，这是client<->server之间的交互，我用的client是本地程序，连接的server是localhost.

老版本(dhcp03)IO性能，Zboot RXA
write(10, "1", 1)                       = 1 <0.000021>
write(10, "1", 1)                       = 1 <0.000022>
write(10, "1", 1)                       = 1 <0.000025>
write(10, "<", 1)                       = 1 <0.000023>
write(10, "/", 1)                       = 1 <0.000029>
write(10, "c", 1)                       = 1 <0.000024>
write(10, "l", 1)                       = 1 <0.000021>
write(10, "i", 1)                       = 1 <0.000025>
write(10, "e", 1)                       = 1 <0.000021>

新版本   Zboot RXA
write(9, "i", 1)                        = 1 <0.000133>
write(9, "l", 1)                        = 1 <0.000112>
write(9, "-", 1)                        = 1 <0.000156>
write(9, "s", 1)                        = 1 <0.000114>
write(9, "a", 1)                        = 1 <0.000118>
write(9, ">", 1)                        = 1 <0.000116>
write(9, "\n", 1)                       = 1 <0.000117>
write(9, " ", 1)                        = 1 <0.000158>
write(9, "<", 1)                        = 1 <0.000123>

后来我把sysctl -a的结果导出来对比，没发现很明显的不同，不同的都是只读的状态值。
谁有经验提供点思路，有可能是什么原因？

我附上两个版本的sysctl内容，第一个是老版本，write系统调用0.000024左右的

所以不一样的是运行的程序？

依云大神来了，运行的客户端一模一样，而且是设备本身的程序，socket连接走的是回环口。

依云 · 2024-09-26 21:46:49

那是哪里不一样呢？

adamzyg · 2024-09-26 22:27:07

依云说：

那是哪里不一样呢？

坦白讲我也判断不出来，内核版本一模一样，内核参数也没看出来什么大的区别。
只是前后版本不一样，我不确定客户的server程序有没有改过socket相关的参数，但是write是系统调用，应该跟linux有莫大关系，但是比较下来又没有证据。
我现在也是想逆向找出证据，所以才有这个问题。

依云 · 2024-09-26 23:02:39

是什么的版本不一样？

adamzyg · 2024-09-26 23:10:28

依云说：

是什么的版本不一样？

这样说吧，这个server程序是客户的，他们说他们没改什么(不能全信)。
我们是乙方比较被动，所以要找到证据是什么引起，因为设备是我们的，我现在比较怀疑他们改过socket相关的参数，但是我得逆向找出证据。

依云 · 2024-09-26 23:32:05

所以服务端变了、客户端是你们自己写的，然后还写成这种鬼样子？？嫌性能不好，那首先你别一个系统调用只写一个字符啊……
另外画个火焰图吧。

这是服务端程序的strace，写成这个恶心的做法了，我提出来了，客户说他们改不了。:-)

依云 · 2024-09-27 10:42:50

哦……画个火焰图吧先。

adamzyg · 2024-09-27 21:21:40

依云说：

哦……画个火焰图吧先。

工具链的原因，想用perf不太好搞。没办法我写了一个测试程序，证明两个版本write性能没有变化，让客户自己去查吧。
谢谢依云~
