In fact, the person who writes Java seems to have nothing to do with the CPU. At most, it has something to do with how we can fully run the CPU and set the number of threads as mentioned above, but that algorithm is just a reference, in many different scenarios, we need to take practical measures to solve the problem. When the CPU is fully occupied, we will also
Recently some of the novice ready to buy a new friend, are asked about the CPU health related issues. These friends must be from where to hear the CPU has a "physical" differences, but as if not clear, how to distinguish. Today to tell you about the CPU of the "physical" what is it?

IBM products are the main bar. As early as the Pentium motherboard bus frequency has 50.60.66MHz three kinds, The frequency of the PENTIUMCPU is generally 75.90.100.120.133.150.166.200.233.266.300.MHz. Motherboard and CPU speed is different, in order to coordinate the speed between the two, in the motherboard generally there is no "frequency multiplier factor" Jumpers are used to set the multiplier relationship between the two, currently popular mothe

0. Why write this blogThe top or PS of Linux can see the CPU utilization of the process, so why do you need to know this detail? There are three reasons for writing this article:* Want to be able to get process CPU utilization in a script in a "non-blocking" way * PS cannot get CPU utilization at the current time of the process; top takes at least 1 seconds to ge
In Linux, you can view CPU and memory usage during system maintenance. you may need to view CPU usage at any time and analyze the system status based on the relevant information. In CentOS, you can use the top command to view CPU usage. After running the top command, CPU usage... in Linux, you can view
For modern CPUs, the performance bottleneck is access to memory. CPU speeds are often at least two orders of magnitude higher than main memory. So the CPU has introduced L1_cache and L2_cache, and the higher-end CPUs have joined the L3_cache. Obviously, this technique raises the next question:If the memory that a CPU needs to access at the time of execution is no
In the Linux operating system, we generally look at the CPU load of the system commonly used commands can be uptime,top, as well as vmstat and so on are all possible. The information provided by each tool is different,I'm going to talk about the CPU section here. Using the uptime command, you can get the operating system in the last 1 minutes, 5 minutes and 15 minutes of the

CPU's frequency, that is, CPU core working clock rate (CPU Clock Speed). It is commonly said that a certain CPU is how many MHz, and this number of MHz is "CPU frequency." Many people think that CPU is the speed of its operation, but it is not. The CPU's frequency indicates
Most users believe that the high-speed download of the Thunderbolt will occupy too high a CPU occupancy rate, which is completely committed to the empirical error. In fact, the thunderbolt can be achieved high-speed, efficient and exist, the overall reduction of CPU occupancy rate.
First, traces of the Thunder Why can reduce CPU occupancy rate

1.0 OverviewIn the Linux/proc file system, you can see the time slices that start at startup, all CPU consumption, and the time slices that the process consumes for a process. This is a cumulative value that can be "non-blocking" output. The process CPU utilization during this time can be calculated by obtaining two statistics of a certain time interval.
So, is there a simple, non-blocking way to get

We have done a lot of articles about CPU, but for most users, we may not have the opportunity to split the CPU in the chassis. Therefore, this time, we will learn about our processor through the system and simple software methods.

Since Intel's 90um technology was launched, its new CPU does not use the previous clock speed to mark the CPU, but uses a number to mark the CPU, which causes Intel's CPU to have a model problem, intel uses this product to fully cover the high-end and low-end markets, but it also raises the consumer's blind choice of
