in general something that use GUI will be heavier, i bet

• GUI tools like DBeaver retrieve and display results within a user interface, which can introduce additional processing time.
• CLI tools output results as plain text, making the process significantly faster.
• Executing the query in the CLI first may prime the database cache, improving performance.
• When the same query is later run in DBeaver, it may seem slower due to the absence of cached data.

Last, more memory will be used for rendering.
