overall performance is improved significantly.2. Compile the new kernel We use this method to compile the kernel: Cancel kernel module support and compile all the server hardware drivers into the kernel, in addition, you must also compile the support for the reiserfs file system into the kernel to increase system security while providing system performance. In versions 2.4.10 and later, the reiserfs file system has been built in. First. Then unlock the kernel file: Tar xvzf linux-2.4.12.tar.g

, if you need to remove the CPU chip, you only need to gently lift the socket wrench to relieve the pressure, and the CPU chip can be easily removed. The PGA package has the following features: 1. Easier plugging and high reliability. 2. It can adapt to a higher frequency. Among intel series CPUs, 80486 and Pentium Pro all adopt this encapsulation form. Iv. bgasphere array Encapsulation With the development of integrated circuit technology,

case of system calls, the ring3 enters ring0, which wastes a lot of CPU cycles. For example, system calls must be directed from ring3 to ring0 (except for the int command called by the kernel, most of which are performed by the hacker kernel module). The level before and after permission escalation is fixed, cpl must be 3, and the DPL of int 80 must be 3, so that the CPU checks the DPL of the gate Descriptor and the CPL of the caller is completely unnecessary. Because of this, intel X86 CPU sta

What is the difference between the Intel CPU Chip T series, the E series, the T series? Intel divides its PC CPU products into the T, E and P three series, and as users of Intel platforms, it is important to understand their differences and to identify the different performance metrics they represent. So, do you know what they mean? What is the best choice when buying a computer? Take a look at the CPU's purchasing guide. The difference between three people: E is the mainstream desktop dual-c

The/etc/profile file contains the system environment and startup program configuration information. when you use-O9 to compile the program, it runs at the fastest speed. Use the-fomit-frame-poinetr option during compilation. when the program is running, the Accessed variable uses the stack. When-mcpu = cpu-type and-march = cpu-type are used, gcc will optimize the CPU model. 　　 If the CPU is Pentium Pro,

difference between the CIDR Block 25 and the d326 is the 478 pin and the 775 pin. In addition, Intel's 775-pin CPU supports 64-bit CPUs, so Sai Yang d326 is still a 64-bit CPU. the intel 3 ** series features a 533 MHz front-end system bus with a level-2 cache of 235 K and does not support hyper-threading. 5 ** is the popular version of Pentium 4. Except for the first 520 and 530 (discontinued) versions, the current 5 ** series are 533 MHz front-end s

processor, the lock# signal generally does not lock the bus, but the lock cache, after all, the lock bus overhead is relatively large. The 8.1.4 section details the effect of the locking operation on the processor cache, and for the Intel486 and Pentium processors, always claim the lock# signal on the bus during lock operation. However, in P6 and the most recent processors, the lock# signal is not claimed if the area of memory that is accessed is alr

are copied to the Des array with an inline assembly. At first, the value of the result variable is 5. But after Movstr (), it becomes 0, and the value is passed through the ECX register, because the rep prefix is used and the ECX value is reduced to 0 at the end of the copy. Next, we execute the Nops () macro. NOPS macro is used to test Rep;nop, see Rep;nop is not going to perform 5 times, if so, then result will turn into 0, but the final outcome is not, but 5. This shows that REP;NOP is not e

chipsets refers to dual-channel DDR memory technology, the main dual-channel memory platform Intel is the Intel 865/875 series, and AMD is the Nvidia Nforce2 series. Dual-channel memory technology is a low-cost, high-performance solution to the problem of CPU bus bandwidth and memory bandwidth. Now that the CPU's FSB (front bus frequency) is getting higher, Intel Pentium 4 has a much higher demand for memory bandwidth than AMD Athlon XP. The Intel
