1. A method for determining software performance, comprising: acquiring, by a server, performance parameters of operation system of running the software of a same version and performance parameters of run software of the same version from various user terminals; processing, by the server, the performance parameters of the operation system of running the software of the same version and the performance parameters of the run software of the same version to acquire a performance parameters processing result according to a preset method for processing a performance parameter; and determining, by the server, the performance of the software of the same version according to the performance parameters processing result; wherein processing the performance parameters of the operation systems of running the software of the same version and the performance parameters of the run software of the same version to acquire the performance parameters processing result comprises: generating, by the server, a performance distribution state diagram for the software of the same version, wherein the performance parameters processing result comprises a performance distribution state curve of the software of the same version; wherein determining the performance of the software of the same version according to the performance parameters processing result comprises: determining, by the server, that the performance of the software of the same version is poor when a ratio of an area value of a region among a performance distribution state curve, a horizontal axis and a right dividing line and an area of a region between the horizontal axis and the distribution state curve is larger than a first preset proportional value; determining, by the server, that the performance of the software of the same version is unstable when a ratio of an area value of a target region and an area value of a region between the horizontal axis and the distribution state curve is less than a second preset proportional value.
