The search keywords window take long time to load "Search term", "Source" and default keywords list first time after open up RIDE.
I want search some keywords by pressing F5 first time after startup ride, the search window no response and then it takes 5 minutes to load search results; please refer to the screenshot:

I closed the search keywords window and open it again, this time the response time just is 2 second; If I close the search keywords window before the search result is displayed, the ride program will be crashed.
And when I "Rename" keywords the spend time still is very long and make the ride window no response.
And when I want "Find Usages" about one keywords, the searching finished time almost 10 minutes.
My test cases, keywords and resource file total size is 7.4M.
Whether have any solution to let the response time shorter?

This needs investigation. The performance sounds really awful.
Thanks for your feedback. Previous RIDE and RobotFramework verisons have this issue as well.
