Part 1 client

1. Compress js and css and put the js before

2. Merge the js/css files on a page and compress the transmission (SquishIt) related blog posts.

3. ajax technology applications. ajax can achieve precise and quantitative requests and reduce unnecessary and repeated requests.

4. Page compression transmission technology (compressing page data. IIS supports gzip compression)

5. uniformly place js/css images on a single server.

6. Client Cache Technology

6.1 StatusCodeResponse. statusCode = 304; this code tells the browser that the requested page has not changed and can be retrieved from its own cache; we need to pay attention to the loss of the cached page. however, the Last-Modified request header setting scheme seems to be unavailable in IE6 7. because the request header is set to Last-Modified, the data value of If-Modified-Since cannot be obtained on the server. Similarly, Etag/If-None-Match cannot be used. therefore, if you want to use this scheme, you must use other comparisons to obtain the expiration time.6.2 set the gtm value of ExpiresString time = DateTime. now. addSeconds (10 ). toUniversalTime (). toString ("r"); Response. addHeader ("Expires", time); note that this method is only valid for the browser press Enter.6.3 Cache-Control: Set max-AgeResponse. AddHeader ("Cache-Control", "max-age = 10"); note that this method is only valid for the browser's carriage return.

 

Part 2 Server 1. Algorithm Optimization for common access methods.

2. cache frequently accessed resources.

3.

Part 3 Database

1. properly establish Indexes

2. read/write splitting

3. Table splitting

Part 4 distributed cache

ASP. NET uses Memcached distributed sessions to improve performance

Part 5 Design Model
