Another clumsy application from Microsoft: cisvc.exe

Also known as content indexing service, this process is part of Windows operating system, and it is supposed to index the files on the drive(s), which should provide faster file search and access using the indexing service catalog.

Faster lookup using VBA Collections

Especially, if the data in particular tables are not changing at all or changing very rarely, we can use this facility and hold the data in memory while the application is running. Beware of the number of records in your table and the amount of memory it may consume.

PHP5: Autoloading your magic!

__autoload() function can be very useful to optimize your code esp. when you have so many classes. Unlike class extensions, optional parameters with class restrictions may not load your class.

So, it’s very encouraging to use classes everywhere! Even encapsulating your functions inside simple classes to use like static modules, will help a lot! …
