You can refer to the following article: http://blog.csdn.net/chixinmuzi/article/details/1727195 The c++ program is the use of map everywhere. Effect of bottleneck program performance is often the performance of map. Especially in the data, and business are closely linked and cannot realize the data distribution and parallel processing. The performance of map becomes the key technology. Said the big data book: "But Hadoop is not rigidly adhere to this way. On the contrary, it is assumed that the huge amount of data makes data completely unable to move, so people must carry on the data analysis in the local." Experience in telecom industry and information security industry, I was dealing with large data base, especially the information security industry data is the most complex, it do nothing without map. For example: IP table, MAC table, telephone numbers, identity card number table query, the Trojan horse virus characteristic code cloud killing etc.. STL map using binary chop, the worst performance. Google Hash map performance and memory is the best, but repeated collision probability. Now I put my algorithm released. There are three kinds of map, build is Hash map. you can find that our algorithm belongs to the zero probability of collision, but also better performance than the hash algorithm. and the performance of ordinary map and Google not much difference between. Procedures for the use of my map is the most direct benefit is the original ten server solution now need only one server Disclaimer: the code can not be used for commercial purposes, for commercial application can contact me QQ 75293192. download address： https://sourceforge.net/projects/pwwhashmap/files/pwwHash.zip/download Field of application: One, Modern war cannot do without the massive information query, if the query targets slow speed for a second, may lead to delay aircraft, resulting in the entire war failed. Information retrieval cannot do wit
