Abstract: Performance testing method and apparatus, an electronic device, and a storage medium, which relate to the field of computer technology and, for example, the field of cloud computing and server technology. The specific implementation includes: in response to determining that current first performance information of a server does not satisfy a predetermined condition, updating current first concurrency according to the first performance information to obtain second concurrency; performing pressure testing on the server according to the second concurrency to obtain second performance information of the server; and in response to determining that the first performance information satisfies the predetermined condition, performing a task allocation operation of the server according to the first concurrency.
