Guilherme Carreiro created DROOLS-3056: ------------------------------------------ Summary: [DMN Designer] Data Types - List View Performance - The view items take 100ms to be instantiated Key: DROOLS-3056 URL: https://issues.jboss.org/browse/DROOLS-3056 Project: Drools Issue Type: Enhancement Components: DMN Editor Reporter: Guilherme Carreiro Assignee: Guilherme Carreiro The creation of a new `DataTypeListItem` [here|https://github.com/kiegroup/kie-wb-common/blob/7f9a51f866fca11f7e7b1...] takes 100ms. This impacts the load time of the Data Types dialog when the user has many data types (e.g. more than 50). To solve this problem, we can pre-instantiate a poll of views and re-use them or take new views from this pool. I just validate this idea with a PoC, and I could reduce 70% of the load time. -- This message was sent by Atlassian JIRA (v7.5.0#75005)
