But the upper class A is still undecided, which cities should be used as the object of protection? Again, owing to the limited funding of co

pressure and improve data processing speed. Some introductions of irqbalance Irqbalance is used to optimize interrupt allocation, which automatically collects system data to analyze usage patterns and puts the working state in performance mode or Power-save mode based on system load conditions. In performance Mode, Irqbalance distributes interrupts as evenly as possible to each CPU to take advantage of CPU multicore and improve performance. When in Power-save mode, the Irqbalance allocates inte

In order to prevent unexpected events, Country A is preparing to build A long line of defense. Of course, if A line of defense is built, the city to be protected must be built inside the line of defense. However, the upper layer of country A is still hesitant. Which cities should

Linux Kernel soft RPS for load balancing and distribution of network reception soft interruptions Routine Linux Soft Interrupt distribution mechanism and problematic Linux interrupt are divided into the upper and lower half. Generally (this is true), the interrupted CPU executes the interrupt processing function, the Soft Interrupt (lower half) is triggered on the current CPU. After the hard interrupt processing is returned, the soft interrupt is star

rps/rfs principle in Linux kernel network In the last chapter, explained the network soft interrupt's mechanism and the optimization in the whole, but in the RPS and the RFS place did not completely explain clearly, only has described its overall function and involves the original intention. This article, further depth and understand the RPS and RFS mechanism. 1

Because the PHP5 platform includes new object models, more new features, and faster processing speed, especially the processing speed of object-oriented Code, although the object-oriented code speed in php 4 is relatively average, however, in PHP5.x, the OSS code speed exceeds the process-oriented speed, so do not doubt the OSS performance. The following test results show all of this. [Test Environment] * CPU: Intel Pentium4 2.66 GHz * Memory: 1 GB * Disk: 73 GB/SCSI * OS: FreeBSD 4.11 * Web: Ap

PHP 4 to the end of this year, the PHP group will no longer support it, so in order to let people more confident transfer to the PHP 5 platform, I specifically did this test, to see if our PHP 4.x is really better than our PHP 5.x pinch, the test results are obvious, that is PHP 5.x The PHP 4.x is faster than PHP 4.x for both object-oriented and process-oriented, so it's absolutely necessary to move on to the PHP 5.x platform to experience the various functions and performance of the PHP 5.x pla
