trex footprint

Java memory can be divided into: heap and meta space. To View the heap: Jmap-heap PID View Metaspace: Use JSTAT-GC pid mc Mu. to view other uses in the process: The RS occupancy in top is minus the footprint in the jmap-heap. /proc/$PID/maps Smaps is a more detailed information Pamp Pid:anon means memory allocation. $cat/proc/1756/maps | grep deleted to search for "Free State of the mmapfile, once the Free State, here will show that the file has been

, so a page can hold more than 8 inode structures, so the inode structure is a small object. Objects less than 512 bytes are called small objects in the Linux kernel. In fact, the buffer is the main memory of a region, dividing the area into multiple blocks, each piece is a slab, each slab by one or more pages, each slab storage is the object. 2, view slab cache information through the Slabtop command Through slabtop we see the Linux system has a large number of dentry cache memory

, the buffer/cached will be quickly recycled. Measurement of memory footprint Measuring how much memory a process consumes, Linux provides us with a convenient way, the/proc directory provides us with all the information, in fact, top and other tools to get the appropriate information. The code is as follows Copy Code Memory usage information for/proc/meminfo machinesThe/proc/pid/maps PID is the process number that displ

look at the process PS aux, this look found the problem, there is a script in the process of a lot of production, Execute the following command immediately to kill: The code is as follows Copy Code Kill-9 $ (PS aux | grep process name |GREP-V grep| awk ' {print $} ') Now look at memory usage, memory is finally normal, OK, and then observe a few minutes, no problem out of the server, continue to check the problem of the script. PS: The thing to emphasize h

As we all know, Windows 8 was launched with several versions, including a Windows RT system for the ARM platform. The ARM platform has some limitations compared to the PC platform, and here's a look at how much memory is occupied. I'm using ASUS TF600T's RT tablet, which is not surface RT, but both use similar hardware configurations and the system is also Windows RT, so the memory footprint can also be referenced. First, let's take a look at the sys

iisapp.vbs, if you and I also prohibit the VBS default affiliate program, then you need to manually go to the directory, select Open mode, and then select " Microsoft (R) Windows Based Script Host "to execute, you can get the corresponding relationship between the PID and the application pool." ）4, to the IIS to view the application pool corresponding to the site, OK, make the above memory or CPU restrictions, or check the program has a dead loop and so on. 5, find out the most CPU-consuming SQ

to do this is because the above operation only in the operating system to the unused space to zero, the virtual machine does not know, so it is necessary to pass this step, so that the virtual machine will not use the space also zeroed.9. Migrate the virtual machine again, change the virtual disk format from "thick provisioning" to "thin provisioning", you can see that the space used to reduce to 10GB, that is, the actual occupied space is actually reduced.The above experiment basically verifie

Yesterday, a colleague in the PHP discussion group mentioned that he did a project because the MySQL query returned too many results (up to 100,000), resulting in insufficient PHP memory. So, he asks, is the data already in memory before executing

There are five scenarios where the local sync folder storage space is not as large as the amount of space that is fast enough for cloud storage. 1. Selective synchronization is set up on the local computer, and some files in the Sync folder are not
