five points: 　　 CPU and chipset cooperation: 　　 Currently, desktop processors are mainly divided into two main factions: AMD's socketa and Intel's socket478, which need to correspond to different chipset, therefore, not any motherboard can use AMD or Intel CPU at will. In addition, users preparing to use a low-end CPU may also encounter a processor with the socket370 structure, such as tulatin celon. At this time, the chipset used is different. To help you understand the relationship between th

mainstream Processor Socket 370 i815ept, sis635, via694tCeleronii, celeon III, Pentium III Socket 462 (socket)Kt400/400a, kt600/600a, nforce2, SIS 746/748 duron, athlonxp, and Yunlong Socket 478I845/865/875 series, SIS 648, via p4x400/400a pentium4, celeron4 The key to determining which processor the chipset supports is the beiqiao chip, which is usually located in the center of the motherboard to the right. You can see the full picture by removing t

suffers a severe performance penalty when exiting the loop because it detects a Possible memory order violation. The PAUSE instruction provides a hint to the processor that The code sequence is a spin-wait loop. The processor uses this hint to bypass the memory order Violation in most situations, which greatly improves processor. For this reason, it is recommended that a PAUSE instruction being placed in all spin-wait loops. Enhance the performance of the spin-wait loops (spin lock loop wait).

system hardware, we should try our best to optimize it during installation. CODE: # groupadd squid # useradd squid add suqid user and user group CODE: # export CFLAGES = '-O2-mcpu = pentium4-march = pentium4-mmmx-msse-msse2' You can select the corresponding parameter GCC-3.1 based on your CPU above can ??? PU optimization: CODE:Pentium2: -O2 -mcpu=i686 -march=i686 -mmmx Pentium3: -O2 -mcpu=pentiu

The critical section pattern refers to the mode in which only one thread can be executed in a shared range.It is the basis of all other multi-threaded design patterns, so I will first introduce it.Focus on the scope. This mode is called the critical section mode. If you place the eye point on the thread of execution, this mode is calledSingle-thread execution mode. First, let's play a cave drill game. axman, Sager, and pentium4. three of them are at t

first access to the proxy request data cache is not, the proxy crawl data will be saved in the cache, so that the speed of access slows down, but the second visitors and later visitors need the information, proxy do not want to remote server request, The data in the cache is sent directly to the subsequent requester, which reduces the traffic to the remote server, and the transmission is faster because the proxy is local. Second, the use of squid in the construction of ProxyServer In this art

processor executes the current instruction, which always causes an explicit bus lock to appear (2) in Pentium4, Inter Xeon, and P6 series processors, the lock operation is handled by either a cache lock or a bus lock. If memory access is cached and affects only a single cache row, the cache lock is invoked in the operation, and the actual area in the system bus and system memory is not locked. At the same time, other
