A task allocation method and system are used for stabilizing a response delay. The method comprises: analyzing at least one query mode according to a target task, and acquiring expected response time of the query mode (102); estimating system overhead information and estimated response time according to the query mode and service description information, and estimating node overhead information processed by each processing node of a system (104); selecting processing nodes according to the node overhead information, and allocating sub-tasks in the target task to the selected processing nodes (106); and determining remaining sub-tasks unallocated in the target task, and scheduling the remaining sub-tasks according to the expected response time, the system overhead information, and the estimated response time (108). Sub-tasks in a target task are processed in batches within expected response time, thereby reducing the overhead of a system on the basis of meeting the expected response time, preventing the response time from being prolonged or stopped due to the problems of the system such as overhead, and stabilizing the response time. |
