Can importing multiple Libraries and Keyword files in all the Test cases using Central Resource file can cause performance issues during execution

问题

Suppose I am creating a central Resource file with name - "Libraries and Resource Files.robot" like below:

*** Settings ***
Library     Library1
Library     Library2
Library     Library3
Library     Library4
Resource    Keyword File1.robot
Resource    Keyword File2.robot
Resource    Keyword File3.robot
Resource    Keyword File4.robot

if I am importing the same file in all of my Test suites like below:

*** Settings ***
Resource     Libraries and Resource Files.robot

Will it make any impact related to the performance of Test Cases execution because there may be a case when all libraries and keyword files are not required for a specific test case. So, will it degrade the performance of the Test Suite execution.
