# Processing Time

Individual tool processing time is displayed in the Database Overview, as shown below:

Processing Time is the average processing time per image in the last processing task, and it is the sum of the processing time and the post-processing time. The processing time for a stream containing multiple tools is not available through the VisionPro Deep Learning GUI, and you cannot estimate it by summing the tool execution time of the tools in the stream because the processing time includes the time required to prepare and transmit view information between tools.

Note: For API, remember that the processing of tools in a stream is always serialized when you call Stream.Process() when considering stream processing. Only one tool is ever processed at a time unless you explicitly process tools individually using Tool.Process().
