s301, acquiring the starting time of starting the execution of the image reconstruction operation by each thread.
In this embodiment, each thread is a sub-thread that performs an image reconstruction operation, and when each sub-thread starts to perform the image reconstruction operation, the reconstruction server main thread obtains each sub-thread start time, and optionally, the start time may be stored in a specified storage space.
S302, acquiring the end time when the actual times of executing the image reconstruction operation by each thread is equal to the preset times.
In this embodiment, each sub-thread executes an image reconstruction operation according to a preset number of times for executing image reconstruction, and obtains an end time corresponding to each sub-thread until the main thread monitors that the actual number of times for executing the image reconstruction operation by each sub-thread is equal to the preset number of times, and optionally, the end time may be stored in a designated storage space.
And S303, determining the period duration corresponding to each thread according to the starting time and the ending time.
In the present embodiment, the main thread determines the cycle duration of the image reconstruction operation performed a preset number of times by each sub-thread based on the start time and the end time of each sub-thread. Optionally, the main thread may also calculate an average cycle duration based on the cycle durations of all the sub-threads and the number of all the sub-threads performing the image reconstruction operation, which is not limited in this embodiment.
Optionally, each thread involves data-based execution and data storage in performing the image reconstruction operation, and in one embodiment, as shown in fig. 4, the method further includes:

And S403, under the condition that the actual times of the thread for executing the image reconstruction operation is equal to the preset times, calculating the period duration corresponding to the thread.
In this embodiment, optionally, each sub-thread calculates the corresponding cycle duration when determining that the preset number of image reconstruction operations are completed, and the calculation manner may refer to the embodiment provided in fig. 3, which is not described in detail in this embodiment.
In the embodiment, the calculation operation and the storage operation of image reconstruction are respectively completed based on different storage spaces, and the image reconstruction operations performed by the first storage spaces of the sub-threads are the same, so that the calculation resources of the sub-threads are reduced.
The image reconstruction operation result is stored based on the second storage space corresponding to each thread, and since the second storage space is limited, the second storage space needs to be monitored and corresponding data processed, in an embodiment, as shown in fig. 5, the method further includes:
s501, traversing the storage memory of the second storage space.

if the parameter value corresponding to each index in the operation state parameters meets the threshold value condition corresponding to each index, determining that the performance quantization result of the reconstruction server is qualified; and if the parameter value corresponding to at least one index does not meet the threshold condition corresponding to the index, determining that the performance quantization result of the reconstruction server is unqualified.
In this embodiment, each operating state parameter of the reconstruction server corresponds to a respective test standard, and after the test is completed, a result of whether each operating state parameter of the reconstruction server is qualified may be obtained, and optionally, if at least one unqualified operating state parameter exists, the quantized result of the performance of the reconstruction server is determined to be unqualified. Alternatively, the performance test result of the replacement reconstruction server may be determined based on the operating state parameters of the original reconstruction server and the operating state parameters of the replacement reconstruction server.
Optionally, the parameter values corresponding to the indexes all satisfy the threshold conditions corresponding to the indexes, including: the actual memory usage rate is smaller than a preset memory usage rate threshold, the actual CPU usage rate is smaller than a preset CPU usage rate threshold, the average cycle duration of image reconstruction operation executed by each thread in the reconstruction server is smaller than the average cycle duration of image reconstruction operation executed by each thread in the original server, the actual test duration of the reconstruction server is equal to the preset test duration, and the number of threads actually executing image reconstruction operation is equal to the preset number of threads. By way of example, table 2 below gives a test example. The preset memory utilization rate threshold is 90%, the preset CPU utilization rate threshold is 90%, the preset test time is 12 hours, and the preset thread number is 1000.

| Index name | Data of original machine | Replacement machine data | Threshold condition (detection standard) |
| Abnormality (S) | Is free of | Is free of | Failure to make an exception |
| Length of operation | 12 hours | 12 hours | >12 hours after |
| Number of threads | 1000 | 1000 | >1000 threads ═ 1000 threads |
| CPU utilization | A％ | B％ | Average<90％ |
| Memory usage rate | C％ | D％ | Average<90％ |
| Average completion time | A first duration s | A second time period s | The time of the replacing machine is not more than 20 percent of the time of the original machine |

In this embodiment, the test result corresponding to each operating state parameter may be determined based on a plurality of operating state parameters of the reconstruction server, the performance test result of the reconstruction server may be determined based on the test result of each operating state parameter, and the performance status of the reconstruction server may be simply and accurately known due to quantization of the test index of the reconstruction server.
In another scenario, the performance result for evaluating the reconstruction server may further include the number of threads for performing the image reconstruction operation, and if the number of threads for performing the image reconstruction operation does not reach a preset default number, the reconstruction server needs to perform a thread starting operation repeatedly, in an embodiment, the method further includes:
and if the number of threads actually executing the image reconstruction operation is smaller than the preset number of threads, returning to the step of executing the image reconstruction operation by calling the threads with the preset number until the number of threads actually executing the image reconstruction operation is equal to the preset number of threads.
The preset number of threads may be 1000, or a default number of threads may be set according to an actual situation, generally, the reconstruction server of the sub-threads with the default number of threads is successfully started, the maximum thread capacity is good, and the bottom line of the self-protection mechanism is high.
In this embodiment, the reconstruction server obtains the actual number of threads for performing the image reconstruction operation based on the main thread, compares the actual number of threads with the preset number of threads, and if the actual number of threads is smaller than the preset number of threads, it indicates that there is a problem of a certain degree in the performance of the reconstruction server.
