Running frequency of robot_localization package in ROS

edit

Hi, I have been confused about what should be the running frequency of the robot localization package in my case, I have wheel odometry being published at 10Hz and IMU data being published at 25hz. What should I keep my robot_localization package running frequency to fuse these two sensors? Should I keep it as same as the one with the lowest data publishing frequency which is 10hz or should I keep it at 25Hz or anything in between and how will it affect the performance of the package?
