Ie6.0,firefox Gzip, The data is then transferred using gzip compression and, if not supported, sent in a regular manner. Therefore, summed up his advantages and disadvantages, excellent: compressed transmission, the speed generally increased twice times. Missing: CPU usage will improve, but through my point of analysis, gzip only access to a page will be compressed, the next time if the page does not chan

Css,js of the website, xml,html can use gzip compression when transmitting, improve the access speed, The image on the website, video and other multimedia files, because the compression effect is not good, so for the picture does not need to support compression, If you want to optimize, you can set the life cycle of the picture a bit longer, so that the client side to cache In nginx.conf, the gzip configura

To optimize the query, avoid full-table scanning as far as possible, and first consider establishing an index on the columns involved in the Where and order by.2. Avoid null-valued fields in the WHERE clause, which will cause the engine to discard full-table scans using the index, such as:Select ID from t where num is nullYou can set the default value of 0 on NUM, make sure that the NUM column in the table does not h

candidates will be generated, resulting in a longer running time. When "FSE = 2" is set, AMAs takes the least ing time, so "FSE = 2" is set to the default value of ASAM. "F" is the frequency threshold of adaptive seed. Reducing "F" reduces the number of candidate hits, thus reducing the ing time. However, a low "F" also causes the seed length to be too long and the seed size of each partition is too small, which reduces the ing sensitivity. In addition, the "f" reduction also expands the Index

Use Index The database index is similar to the index you see in the library: it allows you to get the information you want more quickly, just as the index in the library allows the reader to find the book as quickly as possible. You can create indexes on one column, or on multiple columns. An index is a data structure in which the values of one

-clustered index was built on date Select COUNT (*) from the record where date > ' 19991201 ' and date Select Date,sum (amount) from record Group by date (55 seconds) Select COUNT (*) from the record where date > ' 19990901 ' (' BJ ', ' SH ') (27 seconds) ----Analysis: ----date has a large number of duplicate values, the data is physically randomly placed on the data page under a non-clustered index, and a table scan must be performed to find all the rows in the range when it is searched. ---

This article mainly introduces the use of fastcgi_finish_request to improve the page response speed, has a certain reference value, now share to everyone, the need for friends can refer to PHP FPM provides a method called Fastcgi_finish_request when PHP is running in fastcgi mode. As the document says, this method can improve the processing

to improve the file read and write speed, the general implementation of PHP has little impact, but if you need PHP to frequently manipulate files, the SSD hard disk will play its role.PHP.ini configuration as followsZend_extension=/usr/local/php/lib/php/extensions/no-debug-non-zts-20151012/opcache.soOpcache.enable=1opcache.memory_consumption=128Opcache.interned_strings_buffer=8opcache.max_accelerated_files

This example describes how PHP uses the Memcache caching technique to improve response speed. Share to everyone for your reference. The specific analysis is as follows: Although the PHP has been done very quickly, but if the large amount of data will still have some cards, here is a introduction to PHP using Memcache caching technology to improve response

how to improve computer hard disk read and write speed 1, the computer has a setting is the index hard disk on the contents of the file, this feature will increase the system access to the hard disk, increasing the burden, we can turn it off: in e-disk as an example, open the disk properties, in the General tab, you can see that there is an option to "In addition to file properties, also allow the index of

oracle| Function | speed When data is stored in a normal table, the records are physically saved to the allocated block in the order they were inserted into the database. For example, if you have a table for storing employee information, the employee names will be stored in the table in the order they were inserted into the table. If the employee records a lot, the response time of the datasheet slows down. You can increase the
