.3 The Innodb_log_buffer_size configuration due to the default 1M adjustment to 16MThis configuration item action sets the INNODB database engine write log buffer; Increasing this cache segment can reduce the number of database write data files.4 The Innodb_log_file_size configuration due to the default 8M adjustment to 128MThis configuration item action sets the size of the INNODB database engine undo log, thereby reducing database checkpoint operations.After the above adjustment, the system in

adjusted because of the disaster recovery process involved in MySQL itself.(2) Improve database read Speed, the increase in read speed at the heavy database level is mainly due to several points: simplifying SQL, indexing, and partitioning; the check program SQL is already the simplest and the index has been increased on the query condition. We can only use weap

Reading speed issues for Python dictionaries and listsRecently in the genome data processing, need to read large data (2.7G) into the dictionary, and then the processed data to the dictionary key value matching, in the processed file after each read a row to find out whether in the dictionary keys, the following two code of the efficiency difference is very large:First paragraph:if (Pos in Fre_dist.keys ())

Excerpted a post from a location. The URL is missing. When extracting game resources, I program to use ifstream and ofstream in C ++. However, the speed of reading and writing files is very slow, and the hard drive is crazy, does anyone know how to increase the speed? Thank you! Yang

Recently I have been making my own album software (http://www.tonixsoft.com/ultraalbum/index.php? Lang = CHS) it is slow and depressing to open a large file. I used to use tfilestream to open a file, find the data segment in it, and copy the content to a tmemorystream, the reason for copying it to an independent tmemorystream is that the subsequent processing of a file-type database component must accept the entire tstream as its storage medium, and the entire process is simply unbearable.

A program ape How to make 1 million high-speed, said the specific thing is: How does a fixed worker get out of the inherent pattern and earn relatively good money by other means (investment, wealth management, business, creativity, outsourcing, etc.)? 80% of people will ask such a money problem, but such a problem is too difficult to answer, because it is too difficult to have a standardized m

If you have encountered this, you certainly haven't carefully read the himi blog, in article 19th, himi specifically wrote about the causes and solutions of these errors.

the source code as needed, because manual modification is a much better way to read programs than just reading programs. When you modify and run the program, you can call out the original code from CVS to compare it with the modified part (diff command ), you can see the advantages and disadvantages of some source code and be able to practice your own programming technology. 8. When

different cases. Therefore, it is constantly compared with if-Else, the speed is obviously greatly improved. This also explains why the switch can only use the int type, because the hash of other types is not obvious, which is also the reason for break, because there is no break, the code will be continuously executed in the program segment produced by the switch, and will jump out only when break is encou

Program Code The specific implementation process is introduced. Introduction File operations are one of the most basic functions of applications. Both Win32 APIs and MFC provide functions and classes th

computer uses a data structure called "stack", which is a one-dimensional linear data structure that can complete the call process in the preceding figure. STACK: http://zh.wikipedia.org/wiki/%E5%A0%86%E6%A0%88 Http://en.wikipedia.org/wiki/Stack_%28data_structure%29 The details are as follows: Note the following when reading: 1. At the top of the stack, all functions are being executed. 2. Upper-layer functions are called (deri
