If you have already performed the migration and are working with a large workspace, you can opt to disable the IBM Common Migration UI by clearing its option in Window > Preferences > General > Startup and Shutdown Fresh workspaces
One of these plug-ins is the IBM Common Migration UI, which, when migrating resources into the workspace, detects and suggest changes to those projects if needed. There are plug-ins in RAD that need to always be activated on startup in order to enable some functions. This will reduce memory footprint and also save time that could be consumed during activation of plugins.

Do not install features that are not required Defragmentingĭefragmenting helps with the startup of the product, and also with some I/O intensive, like build and validation. To close it: right click the project and select Close Project. While they remain open, time and memory are consumed in constantly building and validating their source code. Closing ProjectsĪny projects in the workspace that are not being modified or needed as dependencies of other projects should be deleted or closed. You can enable/disable capabilities at Window > Preferences > General > Capabilities.
This will reduce memory footprint and speed up development tasks: Capabilitiesīy disabling capabilities, you can prevent invoking an unneeded function and save time and memory resources by not having a plugin you don't need loaded. If a workspace is large and has a lot of projects that are not frequently updated, convert those to binary form. 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.
