process. Size the number of the process's code, plus the size of the data, plus the total amount of stack space, in kb.tsize the process's code size. This is a very strange value for kernel processes. Dsize the size of the data and stack. TRS text resident size. D is marked as "dirty" page item. The size of the library page that LIB uses. does not work for elf processes. RES the total amount of physical memory that the process occupies, in kilobytes.

The IO performance of a disk is an important indicator of the overall performance of the computer. Linux provides the IOSTAT command to obtain disk input/output (i.e. IO) statistics, and Windows provides a WMI interface that allows you to write a simple script to get the functionality that is equivalent to Iostat. 1, Linux under the Iostat command Iostat-d-k-t 2 The disk IO information is counted every 2 seconds until you press CTRL + C to terminate the program, the-D option indicates the sta

is set to 8. The following example shows to set theEden/survivor spaces ratio to 4: -xx:survivorratio=4 -xmssize Sets The initial size (in bytes) of the heap. This value must is a multiple of 1024 and greater than 1 MB. Append the letter K or K to indicate kilobytes, m or m to indicate megabytes, g or G to indicate gigabytes. The following examples show how to set the size of allocated memory to 6 MB using various units: -xms6291456 -xms6144k -xms6m

applications will set-XMS and-xmx to the same value, avoiding the need to continuously request memory during the runtime. For Java applications, memory consumption is mainly divided into JVM memory consumption and JVM heap memory consumption. Excessive JVM memory consumption can result in frequent GC execution, increased CPU consumption, slow execution of application threads, and even outofmemoryerror, which eventually results in the Java process exiting. JVM heap memory consumption, the most n

will only continue to write to the already-determined disk block. DF Command checks the use of disk blocks, however the du command checks the file system and then counts the blocks used by each directory. Because of this feature of the Du command, when a process occupies a file that does not exist, it does not count the disk blocks that the files occupy. However, the DF command keeps track of the disk blocks used and then reports the use of the disk blocks. If you are interested, take a look at

: Linux Displays the CPU occupancy rate as the first few processes using the command. This command sorts tasks by CPU usage, memory usage, and execution time, and many of the commands can be set in interactive commands or in personal custom files. The top primary field has the following meanings: Table 1. Top field meaning Column Name Meaning Pid Process ID USER User name of the process owner PR Task priority NI Ni
