Original:. NET Edition distributed cache memcached test instance

The following test distributed cache Memcached software, has been learning to pay attention to the large number of Web site cache is how to achieve, before looking at the memcached data, busy no time to really test, this article tests the distributed cache memcached environment is as follows: (two computers as a server)

First station:

Cpu:inter (R) Pentium (r) 4 CPU 2.8G

Memory: 1G

System: Windows 7

Iis:iis 7

ip:172.10.1.97

Environment: Local

Installation: Memcached 1.2.1 for Win32

Second Station:

Cpu:inter (R) Pentium (r) 4 CPU 3.0G

Memory: 2G

System: Windows Server 2003

Iis:iis 6

ip:172.10.1.236

Environment: Remote

Installation: Memcached 1.2.1 for Win32

The test program is deployed to the local environment (172.10.1.97) and the development tool VS2008. NET3.5

This article uses the memcached 1.2.1 for Win32 download address:

OK, let's go through the steps to test the following:

First, to the download of the good memcached 1.2.1 to the C:\memcached directory, respectively, replicated to two servers.

Second, install the memcached service, at the command prompt input CD c:\memcached into the memcached directory, the following figure:

Then enter memcached-h carriage return, look at the help instructions, then enter memcached-d install carriage can automatically install memcached service, the following figure:

Install memcached Service Map

After installing the memcached service, enter memcached-d start carriage memcached Service, as shown in the following figure:

In 172.10.1.97 and 172.10.1.236 two PCs are installed to start memcached.

Third, download. NET Edition memcached client API components to write test programs.

This article uses memcacheddotnet to download the following addresses:

http://sourceforge.net/projects/memcacheddotnet/

After the download, put these files commons.dll,icsharpcode.sharpziplib.dll,log4net.dll,memcached.clientlibrary.dll to the bin directory (none), and then to the test project development Environment Reference me Mcached. ClientLibrary.dll, as shown below

Referencing Memcached.ClientLibrary.dll graphs

Test procedure:

The following are the referenced contents: Using System; Using System.Collections; Using System.Text; Must refer to memcached Using Memcached.clientlibrary; Namespace test { public partial class _default:system.web.ui.page { protected void Page_Load (object sender, EventArgs e) { if (!

EnableCompression = false; StringBuilder sb = new StringBuilder (); Write Cache Sb. Appendline ("Write Cache test:"); Sb. Appendline ("<br>_______________________________________<br>"); if (MC. Keyexists ("cache")) { Sb. Appendline ("Cached cache already exists"); } Else { Mc. Set ("Cache", "Write Cache Time:" DateTime.Now.ToString ()); Sb. Appendline ("Cache has been successfully written to cache"); } Sb. Appendline ("<br>_______________________________________<br>"); Sb. Appendline ("read cache content as follows:<br>"); Sb. Appendline (MC. Get ("cache"). ToString ()); Test cache Expiration Sb. Appendline ("<br>_______________________________________<br>"); if (MC. Keyexists ("Endcache")) { Sb. Appendline ("Cache Endcache already exists, expires as:" MC. Get ("Endcache"). ToString ()); } Else { Mc. Set ("Endcache", DateTime.Now.AddMinutes (1). ToString (), DateTime.Now.AddMinutes (1)); Sb. Appendline (Cache updated write to Endcache, write Time: "DateTime.Now.ToString ()" Expires: "DateTime.Now.AddMinutes (1)." ToString ()); } Profiling Cache State Hashtable HT = MC. Stats (); Sb. Appendline ("<br>_______________________________________<br>"); Sb. Appendline ("Memcached Stats:"); Sb. Appendline ("<br>_______________________________________<br>"); foreach (DictionaryEntry de in HT) { Hashtable info = (Hashtable) de. Value; foreach (DictionaryEntry de2 in info) { Sb. Appendline (De2. Key.tostring () ":" De2. Value.tostring () "<br>"); } } Response.Write (sb.) ToString ()); } }

Five, the operation looks at the effect:

Cache Effect Chart I run memcached-d in local 172.10.1.97

Stops to stop the memcached service, run the above program, as correct, indicating that the cache is also saved to the remote 172.10.1.236 the server. This is a simple way to implement distributed caching, and there is one more option to use the cache. NET with the application and cache, visit a large number of Web sites to achieve distributed caching has many benefits.
