Make sure to have at least 'Build Automatically' and 'Refresh using native hooks or polling' disabled. 'Refresh on access' gets activated only when a file is opened. WDT: 'Build Automatically' exists in the same wizard, but there are two options instead of 'Refresh Automatically': 'Refresh using native hooks or polling' and 'Refresh on access' ( ). RAD: Make sure that 'Build Automatically' and 'Refresh Automatically' options are disabled in Window > Preferences > General > Workspace. If not, this will only spend resources in monitoring for changes caused by external processes. 'Refresh Automatically' is only useful if constantly working with external editors to modify files in the workspace.

When 'Build Automatically' is enabled, each time files are saved, a build is triggered, which makes the save operation itself take longer.

Look below the table for a brief description of each task. Most of these tips can be used also in WDT.This does not mean the tip is exclusive for that condition though.

The table below suggests which configurations might be useful for a few typical conditions you could have in your workspace.

The table in the Performance Tips at the Knowledge Center summarizes the tips, points out the type of improvement and how frequently any of these configuration changes are considered.

If you already have some projects in the workspace, published or not into WebSphere Application Server v7.0 to 8.5.5, you could start by using the Workspace performance tuning tool.

Some of these tips have been integrated to the product into the Workspace performance tuning feature, available by clicking Help > Performance > Workspace performance tuning. The configuration changes listed below can be done to improve RAD's performance depending on individual needs.
