Vs
.Net Analysis
A team of 2 developers rebuilt the “Sun Microsystems’ Java Pet Store J2EE BluePrint Application” using .Net in 4 weeks with 25% of the code. When tested in a lab, the .Net application ran %1000 faster than a tuned version of the Java application. The same Pet Store application was rebuilt by both Microsoft and Sun for an independent competition sponsored by The Middleware Company. Below is a comparison of the results:
| .Net 1.1/Windows 2003 | J2EE/Windows 2000 | |
| Lines of Code | 2,096 | 14,004 |
| Time required for tuning and optimization prior to performance test | 2 man-weeks | 10 man-weeks |
| Price/Performance Ratio – the cost per server divided by the maximum transactions per second the server could handle | $316 – in other words, for a Java application to handle the same amount of website traffic as a .Net application, and additional $989 would need to be spent on server hardware. | $1,305 |
| Maximum Pages served per Second | 1,400 | 600 |
| Maximum Number of Concurrent Users | 6,000 | 4,000 |
| Maximum Number of Transactions per Second | 117 | 59 |
Test Notes: Each application was executed on identical Compaq Proliant servers; J2EE was tested on two Application Servers, one of which crashed midway and did not complete the test; J2EE used an Oracle 9i database while .Net used a SQL Server 2000 database; J2EE ran on Windows 2000 because it outperformed RedHat Linux 7.2 in a trial test.

NET Vs Java Vs Cold Fusion MX Vs PHP
| Feature | .Net | Java | Cold Fusion MX | PHP |
| Compiled Code – Increases website speed (precompiled is the fastest) | Yes – both precompiled and dynamically compiled when a page is requested | Yes – both precompiled and dynamically compiled when a page is requested | Yes – dynamically compiled when a page is requested | No – a 3rd party accelerator can be used to increase performance but it is not installed on most shared hosting servers. |
| Scripted Language – results in poor website performance | No | No | Somewhat | Yes – a 3rd party accelerator can be used to increase performance but it is not installed on most shared hosting servers. |
| Object Oriented – Increases the ability for code reuse and provides enhanced features as well as reduced development time; since code is more reusable, results in fewer bugs that can be discovered by any client and fixed for everyone; encourages developers to write more maintainable code. | Yes | Yes | Somewhat | No |
| Supported Development Languages – easier to find developers | C++, C#, Visual Basic.NET, Jscript.NET, Python, Perl, Java (J#), COBOL, Eiffel, Delphi – 25 languages supported currently | Java | CFML and CFScript | PHP |
| Browser Specific HTML Rendering – different HTML is automatically sent to IE than to Netscape, reducing incompatibility issues | Yes | No | No | No |
| Open Source | No | Yes | Somewhat | Yes |
Horizontal Vs Vertical portal (Vortals)
Two broad categorizations of portals are horizontal portals and vertical portals(vortal).
horizontal portals : cover many areas (another meaning: used as a platform to several companies in the same economic sector or to the same type of manufacturers or distributors.)
vertical portals : which are focused on one functional area(another meaning : a specialized entry point to a specific market or industry niche, subject area, or interest.
