Many companies are upgrading their wireless networks to 802.11n to achieve greater throughput, wider coverage, and greater reliability, while ensuring the performance of wireless LANs (WLANs) is particularly important to ensure adequate network capacity and coverage. Below, we'll explore how to measure network performance through IPERF, a tool that is easy to use to measure tcp/udp throughput, loss, and latency. Pre-application Preparation Iperf is

main cache mode: Buffer Cache and Page cache. The former is for the disk block read and write, the latter for the file inode read and write. These caches can effectively shorten the time for I/O system calls (such as read,write,getdents). Remember that the memory is for use, not to take a look. Unlike windows, no matter how much of your real physical memory, he will have to take the hard disk swap files to read. This is why Windows often prompts for a lack of virtual space.

the core Httpry program was a set of parsing scripts for mining information out of generated log files. Most of these scripts is written as plugins for a core parsing script and include functionality for extracting search ter MS, searching for specified terms within client flows, and outputting the logs in XML among other things. It is relatively straightforward to write custom plugins for additional parsing tasks.Latest NewsThe latest release adds a number of useful features and tweaks. VLAN t

Sysstat monitors CPU usage, hard disk, and network throughput data. The collection and analysis of these data helps us determine whether the system is running normally, it is an effective assistant to improve system operation efficiency and secure operation of servers. Sysstat writes the plan log in/etc/cron. d/sysstat. The log is recorded every 10 minutes, and the log process of the day is summarized and cut. The SAR command displays the CPU running status by default. SAR Command Options -B

The simplest and most direct method is to add -VVParameters to print the request and corresponding information of each client on the console, which is very suitable for development. Another direct method is to use Telnet. For example, if the server is a port 11211 of the local machine, you can use Telnet local host 11211 And then use StatsTo view the server status. In addition, a better choice is to use some specialized monitoring tools. Some e
