computing technology are unable to solve massive data mining due to low mining efficiency, affecting the timely extraction of data. For a long time, business intelligence systems are often built based on traditional SMP architecture minicomputers. With the increasing performance, availability, and scalability of the x86 Platform in recent years, the X86 platform has begun to erode the share of minicomputers in more and more market fields, business Intelligence has also become another battlefi

programmers. When writing code, you should not rush to implement the function. If you want to write code, the code execution efficiency is better. For example, suppose there is a shortcut for defining getelementbyid functoin $ (elemid) {return document. getelementbyid (elemid)}, someone may write this code $ ("mydiv "). parentnode. removechild ($ ("mydiv"), in fact, the getelementbyid Dom query is executed twice here. It will be better if it is changed to this: var mydiv = $ ("mydiv"); mydiv.

Make full use of CPU Performance Now we are trying to capture packets, and how to maximize the performance of the server becomes a problem facing us. Today, we will introduce the CPU performance configuration items. 1. First check the current CPU physical frequency and operating frequency in the Linux system, in the following you will find that our CPU is 2.0 GHz E5-2620, but the CPU is working in 1200mhz. cat/proc/cpuinfoprocessor:0vendor_id:GenuineIntelcpufamily:6model:45modelname:Intel(R)

previous 32-bit X86 architecture applications, protect your previous investments; while Intel's itanium and itanium 2 series Processors require additional software or hardware for compatibility with previous 32-bit programs, so IA-32 (I .e. x86-32) x86-64 are x86, that is, Intel's 32-bit X86 architecture, such as Intel's 32-bit server Xeon (Xeon) processor series, AMD's full range, in addition, the full ra

same size. For example, a continuous page (4 K) can be divided into 32 128-byte objects.Allocation of small objects The size of each small object is mapped to one of the 170 allocable dimension classes. For example, 961 to 1024 bytes are normalized to 1024 bytes. The dimension classes are separated as follows: smaller sizes differ by 8 bytes, larger sizes differ by 16 bytes, and larger sizes differ by 32 bytes, and so on. Maximum interval (for dimensions> = ~ 2 K) is 256 bytes. A thread cache c

The CPU freq tool is used to temporarily adjust the clock speed of the CPU. the CPU and the main board have power-saving technologies. If the CPU is working at a low load, the frequency is automatically reduced. If you need to temporarily set the clock speed and working mode, you can use cpufreq to manually adjust it. This mode will expire after restart. If you need to adjust it for a long time, modify/etc/sysconfig/cpuspeed. Www.2cto.com lsmod | grep "acpi_cpufreq" run the preceding command to

Compared to Intel's 64-bit server processor products, the x86-64 has the biggest advantage of being fully compatible with the previous 32-bit X86 architecture applications, protection is based on users' previous investments.

The performance of the motherboard With Different chipset designs is also different, and some of them are integrated into the motherboard, which needs to be carefully identified

The xw6200 and xw8200 are based on the intel e7525 (codenamed tumwater) chipset and support the latest 'nocona 'Xeon processors, the selling point of this processor is that it uses Intel's 64-bit extended memory technology (Intel em64t). In other words, this processor has the ability to run 64-bit code and use more memory, theoretically, up to TB of memory can be managed. It meets the needs of users in high-end PC environments, such as computer-aided
