one that consumes the highest CPU.
If you are unwilling or unable to install Htop, you can use the following command:
shps aux --sort=-%cpu | awk 'NR==1{print $2,$3,$11}NR>1{if($3!=0.0) print $2,$3,$11}' > some_file.txt
This command sorts the user process by CPU usage and outputs it to the some_file.txt, and you see t
CPU Ladder Figure 2016 the latest version of the CPU how to see performance?
How does the CPU look at performance? This is a problem that friends of computer enthusiasts often ask. Today, the script House finally brings up the latest version of CPU Ladder 2016, through the
Do you want to know the performance of your CPU?Do you think the testing software is too troublesome?Do you think it would be great to have free testing software?
Now, you can download my own test_cpu program to test your CPU performance ~Simply run the test_cpu.exe program in double-click mode. Wait for 30 seconds to 2 minutes (depending on the performance of the machine) and you will

I wrote an sort algorithm to test the speed, but the 100 x W has exceeded the 32-bit limit. The 32-bit PC should be the power of 2, I hope a friend with a 64-bit CPU can test it. Of course, don't forget to tell me the result.

Today ran a very time-consuming bulk insert operation. When using the top command to view the CPU and memory usage, the CPU was checked by 120%. Never noticed before. By pressing 1 on the big keyboard in the case of top, the number of cores viewed by the CPU is 4 cores.By looking through the Web, the top command shows the total number of CPUs your program consume
MySQL query consumes CPU time, help me to see how to optimize this MySQL structure
$SQLL = "Select * from ' shops ' WHERE ' subdomain '! = ' ORDER by RAND () LIMIT 15";
Only use this query, to subdomain query, this MySQL CPU time is very high, Sina app This wants money, do not know how to optimize can reduce MySQL CPU
