Embodiments of the present disclosure relate to improving computer performance. An action may be issued to a first client and a second client. A first optimization factor list (OFL) may be generated for the first client and a second OFL may be generated for the second client. After each OFL is generated, the first OFL may be compared to the second OFL. A correlation factor (CF) may be generated between the first client and the second client based on the OFL comparison, wherein the CF indicates a level of similarity between the first client and the second client. A bottleneck causing performance issues in the first client may be determined and computer configuration of the first client may be adjusted based on the bottleneck.
