Previously on the Internet to see a tutorial on the production of tornadoes, is using Mel to control the particle's motion path to achieve the appearance of the tornado. Now this tutorial is going to use another method to achieve this effect. By building a tornado model, making deformations, adding particles to complete, now let's start. 1, the first to make a tornado model, is a radius from small to large spiral, I used the Createtube this Mel, you can use their familiar method to create. This

programs implementing KeepAlive, but can easily add keepalive support for most of them follow ing the instructions explained later in this document.3.1. Configuring the KernelThere is ways to configure keepalive parameters inside the kernel via userspace commands: Procfs Interface Sysctl Interface We mainly discuss how this was accomplished on the PROCFS interface because it's the most used, recommended and the easiest To understand. The Sysctl interface, particularly regardin

In the Apache, PHP, MySQL architecture, MySQL has the greatest impact on performance and the key core. For the discuz! Forum program is also the case, MySQL settings are reasonable optimization, directly affect the speed and load of the forum! At the same time, MySQL is also the most difficult part of optimization, not only need to understand some MySQL expertise, but also need a long time to observe statistics and based on experience to judge, and then set reasonable parameters. Below we unders

Only if you expect to have a lot of connections in a short time, you need to increase it, in other words, this value is the size of the listening queue for incoming TCP/IP connections. Your operating system has its own limits on the size of this queue. Attempting to set Back_log above your operating system will be ineffective.When you look at your host process list, find a lot of 264084 | Unauthenticated user | xxx.xxx.xxx.xxx | NULL | Connect | NULL

(1) CPU: Determine the speed of operation, such as Celeron D2.66g, where "2.66G" refers to its operation speed, but here the unit "G" with the hard disk "G" is different, not the size, the CPU "G" is the "GHZ" is the frequency, that is, can operate 2.66G times per second; (2) Motherboard: Determine the op

for such a working environment. Be careful not to buy some "soft" raid cards, so that, although the purchase price is lower, But its performance is poor and consumes a lot of system resources. Iwill's side RAID100 is a good choice. The hard drive recommends using a 5400-RPM model. Because after using RAID to set up an IDE array, overall disk performance is approximately n times the size of a single hard drive. This depends on the number of your hard drives.

The combined use of the above technologies not only ensures the stability and reliability of wireless coverage, but also increases bandwidth and coverage capabilities, making the development of wireless networks more economical. In the context of high bandwidth application speed, rural villages and towns with huge network access needs are experiencing a wave of rapid advances in wireless access applications. At present, the rural wireless coverage application product

disgusting ...... One day, I found out that memcached and memcached are a cache system. In this case, if there is a query statement, it will take a lot of time. If there is no cache, the database will be accessed every time you refresh the page, in this way, the database pressure is relatively high. If there is a cache, it will be different. If the data to be queried exists in the cache, it will be retrieved directly from the cache, so that you do not need to go to the database for query, if t
