Assuming that the parent process waits for its children then the total CPU usage can be calculated from utime, stime, cutime and cstime: utime %lu Amount of time that this process has been scheduled in user mode, measured in clock ticks (divide by sysconf(_SC_CLK_TCK...
Logical cores, on the other hand, are based on the concept of hyperthreading. Simply put, hyperthreading is a feature that divides a physical core into multiple (usually two) logical cores. The number of logical cores can be calculated by multiplying the number of physical cores by the threa...
My search-fu is failing me. I just can't find any mention of how it's done other than a lot of C/C++/C# developers writing custom DLLS based on stupidity like the serial number of the disk and CPU. John Nelson #2 Saturday, August 2, 2014 6:09 AM | 1 vote A bit more detailed...
It's interesting to note that the page size supported by the 80386 is somewhat close to the page size supported by the Atlas, even though the 80386 was designed about 20 years later and computers (and the workloads they ran) have evolved radically during that period of time! In...
Knowing how much of your CPU is in use can be crucial to diagnosing performance issues. Here’s how.
When the computer is running, the CPU will transfer the data that needs to be calculated into the main memory for operation. After the operation is completed, the CPU transmits the result, and the operation of the main memory also determines the stable operation of the computer. The main me...
CPU Core Ratio, or multiplier, determines the speed of your CPU. The overall speed of your processor is calculated by multiplying the base clock speed (BCLK) by this ratio. For example, a BCLK of 100MHz multiplied by a CPU core ratio of 45 would result in a CPU speed of 4,500MHz, ...
A new Excel file with the same values might not have underlying formatting which is using up more CPU time. Method 9 – Use Excel Tables and Named Ranges Tables allow you to streamline cell referencing and formulas, which can cut down on computation requirements. ...
Time to First Byte (TTFB) Each of these metrics is measured and then scored according to the level of performance. When you run a PageSpeed Insights report on your site, you’ll receive a score and a “grade” for each of these, which will fall into one of three buckets: ...
The time origin The time origin is a standard time which is considered to be the beginning of the current document's lifetime. It's calculated like this: If the script's global object is a Window, the time origin is determined as follows: If the current Document is the first one loaded...
