No matter how careful you are, it is impossible to completely avoid bad code. At this time, some tools are required to help us check whether there is any place in the code that will cause memory leakage. The ddms in Android tools comes with a very good memory monitoring tool heap (here I use the ADT plug-in of eclipse, and take the real machine as an example, the situation in the simulator is similar ). To

Erlang has provided a series of tools to view the running status. Is there any Web monitoring tool available?

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.
