The invention relates to a processing method and device for read-write overtime and a computer readable storage medium. The method comprises the steps that all read-write operation occurring in a preset time period is acquired; when a preset duration from terminal time in the preset time period is up, whether all the read-write operation is completed is determined; and when at least one time of read-write operation in all the read-write operation is not completed, a first timer sets read-write operation overtime in the preset time period, and a second timer is reset. Through the technical scheme, the previous operation that overtime needs to be set once every time read-write operation is completed is optimized to be the operation that only one time of time reset is performed in a certain time period. Due to the fact that it is unnecessary to set read-write overtime in each time of communication under the condition of a big data volume, performance loss caused by overtime setting can besubstantially lowered by stripping timer logic, and the effect of performance optimization is achieved.
