The server administrator needs to have high skills in """Server **Optimize and Tweak High-Traffic Servers tools""""

**

*MapReduce

* Hadoop

* Apache Cassandra,

* Memcached

*Load balancer in front of webserver nodes,

*Load Balancer Node

*Web Servers Node

*Database Server Node

*CISCO

Compression:

fastbid guide [][7][[url removed, login to view]~kewu/fastbit/doc/[url removed, login to view]][8]

and other kind of compression server tools

**For server performance:**

The coder needs to know how not to use Apache with PHP cause it will kill performance and be abel to Use **lighttpd or nginx with FastCGI"**

*Dedicated database server with RAID-10 array with 8 or more disks,

*Nodes - multiple nodes,

*Install **xcache** on all php boxes,

*Tune Linux **TCP/IP stack**,

*Apache Memory Use Optimization,

*Vertical Scaling vs. Horizontal Scaling,

*Clustering servers all together,

*** ProxyWeb Server**

Storing Structured Data in BigTable, repartition of all server files in order

for all server content may be deployed confortably such as tomcat, etc..

*** TUX / "Red Hat Content Accelerator"**

<[url removed, login to view]>

kHTTPd - <[url removed, login to view]>

thttpd - <[url removed, login to view]>

*** lingerd

** Lingerd takes over the job of feeding bytes to the client after Apache has

fetched the document, but requires kernel modification. Sounds pretty good,

haven't tried it. lingerd - <[url removed, login to view]>

*** Being abel to Replace Apache completely** with something

more scalable. Currently, the best options appear to be servers that use a

non-blocking I/O technology and connect to all clients with the same process.

That's right - only ONE process. The best include:

*** thttpd** - <[url removed, login to view]>

*** Caudium** - <[url removed, login to view]>

*** Roxen** - <[url removed, login to view]>

*** Zeus** - [[url removed, login to view]][9]

*** HAproxy** open source or hardware loadblancer

**Solutions: PHP's CPU & RAM Usage**

*** Turck MMCache** open source PHP accelerator

Accelerator and all other PHP accelerators in benchmark tests. So it's

currently the BEST PHP accelerator around, even against commercial products,

despite being free.

*** Use "TOP" and "PS axu"** to check for processes that are using too much

CPU or RAM.

*** Use "netstat -anp | sort -u"** to check for network problems.

*** Varnish;** is an HTTP accelerator designed for content-heavy dynamic web sites.

Varnish was designed from the ground up as an HTTP accelerator.

*** lingerd** - <[url removed, login to view]>

Lingerd takes over the job of feeding bytes to the client after Apache has

fetched the document, but requires kernel modification.

*** The Cache_Lite class comes courtesy of PEAR, the "PHP Extension and

Application Repository"** ([[url removed, login to view]).][10]

In case you didn't know, PEAR

is an online repository of free PHP software, including classes and modules for

everything from data archiving to XML parsing. When you install PHP, a whole

bunch of PEAR modules get installed as well; the Cache_Lite class is one of

them.

* Setting the " RAM Cache for HTTP Traffic"

*** Openx Cluster:** High performance simple cluster based on **Nginx, lighttpd/apache

**
