This topic contains tips to improve the overall performance of the Clarion IDE on your computer, and the minimum and recommended system requirements.

General tips:

1.Turn off virus checking on the Clarion.exe program.

2.Defragment your hard disk after you install Clarion.

3.Check that your system meets the RAM and processor recommendations and then consider whether to upgrade the memory or disk speed.

System Requirements:


1.6 GHz CPU, 384 MB RAM, 1024×768 display, 5400 RPM hard drive


2.2 GHZ or higher CPU, 1024 MB or more RAM, 1280×1024 display, 7200 RPM or

higher hard drive. If Running on Windows Vista: 2.4 GHz CPU, 768 MB RAM

IDE Tips

When you have the Clarion integrated development environment (IDE) open:

1.Before you exit the IDE, close the pads that you do not use at startup. This can increase your startup speed the next time that you start the IDE.

2.Do not display the Properties Pad at startup. The Properties Pad displays automatically when you open a solution.

Processor and Memory

For the best performance of the Clarion IDE, you want to get a dual core or better CPU. We also recommend getting at least 2GB or more of RAM. Make sure you always get the fastest possible hard-drive when buying a new machine - and where necessary trade off purchasing additional CPU processor speed in favor of a faster disk instead.

Hard Drives

The default hard drive speed for most PC laptops is typically 5400rpm - which is a pretty slow drive in comparison. If you are getting a new laptop and plan to use Clarion on it, we recommend making sure you get a 7200rpm drive instead. You will realize a significant performance benefit by doing this.

For a desktop machine hard drive, consider getting a 10000rpm hard drive, or even better a 15000 RPM drive. These make a very big difference over the default 7200rpm drives that typically come with desktops. You should also check the drive's cache size. Older drives have 1MB or 2MB of cache. But you can get drives with 8MB and 16MB caches which will speed up the performance of the drive.

You could also consider buying a second physical hard drive and setup your operating system and OS virtual memory swap file to use one of the physical drives, and store all your data on the second physical drive. The benefit is that your read/write data operations won't be competing for disk I/O activity with the operating system updating the virtual memory file.
