Stop Log Daemon syslogd.
停止日志守护进程syslogd。
For example by using init-scripts:
例如通过使用初始化脚本：
/etc/init.d/syslogd stop
Depending on your Linux-Dist this can be achived in different ways. For disable logging permanantly (embedded system with low disk space) remove loggind deamons, edit /etc/defaults or remove init scripts from the rc (runlevel-configuration) directories.
根据您的 Linux-Dist，这可以通过不同的方式实现。要永久禁用日志记录（具有低磁盘空间的嵌入式系统），请删除 loggind 守护程序，编辑 /etc/defaults 或从 rc（运行级别配置）目录中删除 init 脚本。
Edit: much more of interest would be, what causes your latency problems. I do not believe the logs would cause this. Run "top -d1" and check the most upper processes. A network home server for example would probably not need the XWindow System. If you are not running web-development on this machine also Database and Webser will probably be of no need... A lot of processes can cause lags.
编辑：更有趣的是，是什么导致了您的延迟问题。我不相信日志会导致这种情况。运行“top -d1”并检查最上层的进程。例如，网络家庭服务器可能不需要 XWindow 系统。如果你不在这台机器上运行 web 开发，那么数据库和 Webser 可能也不需要......很多进程会导致滞后。

Syslog has been replaced by rsyslog on numerous OS. So, on Debian > 5, Ubuntu > 11.2, Centos 6.x the following command line would stop it:
在许多操作系统上，Syslog 已被 rsyslog 取代。因此，在 Debian > 5、Ubuntu > 11.2、Centos 6.x 上，以下命令行将停止它：
service rsyslog stop
Then, you can disable it at boot:
然后，您可以在启动时禁用它：
systemctl disable rsyslog
to enable it again at boot:
在启动时再次启用它：
systemctl enable rsyslog

If (like some of us) you have really old legacy systems:
如果（像我们中的一些人一样）你有非常旧的遗留系统：
% /etc/init.d/syslog stop
% chkconfig syslog off
