Improving Application Performance (Part 2)
Not all queries can be saved as an application variable. For Queries that do not meet the checkpoints in my previous tutorial there is another way to improve performance. Query Caching is another way to save data and eliminate unnecessary queries. This is for queries that are more dynamic in nature.

Improving Application Performance
One thing I am always trying to do is speed up my applications. As my site grows in size and complexity I find that I spend a fair amount of time re-coding pages because of a new technique I just learned. I wish I had learned about these techniques long before, and thereby allowing me to create more effective code. In this tutorial I'll try to explain some problem areas that I have identified, and some of the things you can do to improve performance.

Random String/Password Generation
This is a custom tag I wrote that generates a random string at the set number of characters using the characters you decide on Alpha AlphaNumeric or Numeric Uppercase, lowercase, mixed case... It will create a variable that you name as you wish and call however you'd like. It is a small example of how to create a custom tag and will hopefully send someone in the right direction. It is also fully functional and has come in handy quite a few times. Enjoy and as always.. Have Fun!

Boost your applications performance with cached CFCs
When using the cfinvoke tag or the CreateObject function on your pages, it adds CPU time to process the requests to load all of those objects into memory. Under load this can make quite a difference in your page response times. One way to get around it is to put those objects into a shared scope so they only get instantiated once. This will save memory and CPU time on your server.

Simplify form development and processing
Have you ever wanted to have a quick way to process just about any form in coldfusion? If you can apply some simple standards to your database and to your form elements, then this tutorial makes it easy for you to rapidly develop and deploy your application. Note, some developers will frown on it because it does not draw on stored procedures where efficiency can be gained in your application, but sometimes you just want to get it working - you can let the hard core programmers use the prototype to make it work more efficiently. They will like you for using less code.

Custom Tag for Multiple Related Text Boxes
hi, I saw some tutorials on may sites which show how to develop related select boxes using cold fusion and javascript. Many of them were titles "Multiple Select Boxes" which was a bit un-appropriate as they did not really show how many levels of heirarchy they would cover. So, I finally decided to develop a custom tag that would help developers to simply implement a "n" level of select boxes using hierarchial data. thanks, Saurabh
