generation of machine code is unlikely to be identical, can only hope that the difference is not large. From slowest to fastest analysis: 1,unity script Minmax2 Same MonoDevelop compiled with C # DLL 2,unity script Minmax1 3,c# dll with C # DLL MINMAX2 CIL code:IL_0041 is the start of the For loop, ilxxx ends with B are branch branch jumps, the for Loop has 4 branch jumps, it appears that the three-dimensional operator translated into 4 if. Machine code:Red Line within the range is for loop, lo

Label:Currently in a project optimization, want to analyze SQL Server system performance through the database layer, check the online code, modify the title and DMVs code, the following code can be used to analyze the system after a period of time, those statements are system busy SQL statement. As a reference. Alternative use: Once in the analysis of a reconciliation function, look at the system code, read half a day, write too irregular, and do not write comments, can not understand. Finally,

very good mechanism to solve the blocking problems caused by the large number of data cases,Makes Nginx's performance reach a new height.As mentioned earlier, there is a new interface that could implement the "remove" task mechanism without lossy performance.Note: Some of the translations in the original(1) Offloading translation for unloading, in fact, is to put a task into the task pool;(2) It is mentioned in the original text that the task is offloading to the thread pool, but in fact it is
