The current mode of mechanical disk operation, mainly reflected in the disk reading and writing to find the track of the process, the disk caching function for reading and writing speed is very important. Disk search process is a mechanical way, so that its random speed is significantly lower than the sequential reading and writing, generally ordinary disk IO can reach 40--60MB per second, slightly better w

When I had nothing to do at night, I suddenly wanted to test the connection speed improvement caused by the ADO. net connection pool. I wrote the following:Code: Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/--> 1 Using System; 2 Using System. configuration; 3 Using System. Data. sqlclient; 4 Using System. diagnostics; 5

As mentioned above, we can only optimize the code that affects the speed. The Benchmark_Timer class and Benchmark_Iterate class in the benchmark package of PEAR can be used to conveniently test the speed of script execution. (For installation and configuration of PEAR, see relevant information ). First, use the Benchmark_Iterate class to

Ubuntu11.10 is coming soon. On the eve of its arrival, foreign Netizens found that its (OneiricOcelot version) boot speed was unsatisfactory. Whether it's PC or laptop, Intel CPU or AMDCPU, or traditional hard disks or SSD, Ubuntu11.10 is not as fast as previous versions. On Multiple test platforms, the boot speed of Ubuntu11.10 is better than that of Ubuntu11.04

Early to hear that is C + + running speed than C is a lot slower, so write a small program to test, in the end how slow.1#include 2#include 3#include string.h>4 intMain ()5{clock_t a=clock ();6 inti,j,k;7 Charc[10000]={"ASSDASDXZCZASDXZCZZSDAAAASDXZCZZSDAAAZSDAAAAAAAAAAAAAASDASFSDXZCZZSDAAAAAAAAAAAAAASDASFZVFASDQWEASFASSDXZCZZSDAAAAAAA AAAAAAASDASFZVFASDQWEASFASSDXZCZZSDAAAAAAAAAAAAAASDASFZVFASDQWEA

As mentioned earlier, it is possible to optimize only if we find code that affects speed. The Benchmark_timer class and Benchmark_iterate class in the Pear benchmark package can be used to easily test the speed of script execution. (For pear installation and configuration, please check the relevant information yourself). First, use the Benchmark_iterate class to

Copy is also called copy. We do not know how many operations are performed every day, but do you really use it? Sometimes, simple copy operations may also encounter some minor issues: the copied text is changed to garbled, encrypted Web pagesArticleCannot be copied. How can we solve these problems? This article will show you an answer, and you can also see how to speed up replication and other related skills. Required Course for copying 1. learn f
