The invention provides a data processing method and a server cluster. The data processing method is applied to a server and comprises the following steps that: determining a target timing task; obtaining the execution starting time of the target timing task; before the execution starting time of the target timing task begins, loading the data of the target timing task into memory so as to be convenient in directly reading the data of the target timing task from the memory when the target timing task begins to be executed; quickening the data reading speed of the task timing task so as to improve the data processing efficiency of the target timing task to lower data calculation pressure and obviously improve calculation performance in a timing task set.
