Methods, apparatus, systems, and articles of manufacture are disclosed to synchronized threads. Example apparatus disclosed herein identify a first trigger frequency associated with a first application thread, the first trigger frequency corresponding to first times of first requests associated with the first application thread. Disclosed example apparatus also identify a second trigger frequency associated with a second application thread, the second trigger frequency corresponding to second times of second requests associated with the second application thread, the second trigger frequency different from the first trigger frequency. Disclosed example apparatus further determine a third trigger frequency based on the first and second trigger frequencies, and adjust at least one of the first requests or the second requests to the third trigger frequency.
