Essential Guide to Checking RAM Usage on Linux

On a old machine (512 MB RAM) I am currently running ubuntu jaunty and firefox 3.0.15. I tried the ad blocker addon add block plus but it eats lots of RAM (>300 MB). Is high memory load of this add-on a bug, which is fixed in a newer version or just normal? If so, why is the memory usage so high?Is there another ad blocker add-on for firefox, another browser- add-on combination for linux (ubuntu jaunty) or even better a browser independent solution for linux which uses significant less RAM? asked Jun 16, 2012 at 14:40 studentstudent4852 gold badges11 silver badges39 bronze badges 1 ABP acknowledges on their forum that they have a significant memory overhead, so if you want to get your RAM usage down you will have to switch to something else. You could always try an ad-blocking HOSTS file, which wouldn't waste RAM. This particular one is regularly updated, but be sure to check it over before adopting it and make a backup of your original to be safe, of course.

M-functions. To create a function M-file that can be called in-place, you must ensure that the output argument matches one of the input arguments. The ability to call functions in-place (introduced in MATLAB 7.3) is available only when the function itself is called from a function M-file and not from a script.As mentioned earlier, in-place operations result in reduced memory consumption as well as reduced computation time. Figure 6 shows the memory usage in the Windows Task Manager during the execution of code segments 1 and 2 processing a 100-million element array (stepped through manually with the debugger to make memory changes more obvious). Figure 6. Memory usage logged over time as code segments 1 and 2 execute. Click on image to see enlarged view. Reduced memory usage is particularly important when dealing with data sets that are larger than the available RAM. Operating systems supplement physical RAM memory with a swap or page file stored on disk. Accessing data stored on disk is orders of magnitude slower than accessing data stored in RAM, however. For maximum performance, keep memory usage low enough to prevent your system from running out of RAM when MATLAB is executing. Memory Performance Glossary Cache.

Is a dedicated option --low-memory which influences decisionsof Nuitka, such that it avoids high usage of memory during compilationat the cost of increased compile time.Avoid 32 bit C compiler/assembler memory limitsDo not use a 32 bits compiler, but a 64 bit one. If you are using Pythonwith 32 bits on Windows, you most definitely ought to use MSVC as the Ccompiler, and not MinGW64. The MSVC is a cross compiler, and can usemore memory than gcc on that platform. If you are not on Windows, thatis not an option of course. Also using the 64 bits Python will work.Use a minimal virtualenvWhen you compile from a living installation, that may well have manyoptional dependencies of your software installed. Some software, willthen have imports on these, and Nuitka will compile them as well. Notonly may these be just the trouble makers, they also require morememory, so get rid of that. Of course you do have to check that yourprogram has all needed dependencies before you attempt to compile, orelse the compiled program will equally not run.Use LTO compilation or notWith --lto=yes or --lto=no you can switch the C compilation toonly produce bytecode, and not assembler code and machine code directly,but make a whole program optimization at the end. This will change thememory usage pretty dramatically, and if you error is coming from theassembler, using LTO will most definitely avoid that.Switch the C compiler to clangPeople have reported that programs that fail to compile with gcc due toits bugs or memory usage work fine with clang on Linux. On Windows, thiscould still be an option, but it needs to be implemented first for theautomatic downloaded gcc, that would contain it. Since MSVC is known tobe more memory effective anyway, you should go there, and if you want touse Clang, there is support for the one contained in MSVC.Add a larger swap file to your embedded LinuxOn systems with not enough RAM, you need to use swap space. Running outof it is possibly a cause, and adding more swap space, or one at all,might solve the issue, but beware that it will make things extremelyslow when the compilers swap back and forth, so consider the next tipfirst or on top of it.Limit the amount of compilation jobsWith the --jobs option of Nuitka, it will not start many C compilerinstances at once, each competing for the scarce resource of RAM.

The full path of the file.du -h ~/test4.0K testHere ~ means the home directory in Linux. From the command output in our example, we can see that the size of file test is 4.0K.In bash, we can use the following code to get the file size only.filesize=$(du -h /etc/passwd | awk '{ print $1}')echo $filesize4.0KIf you need to get the size for all the files under the current directory, you can use this command.du -h *Now we know that we can use du command to get the size of file . Can we use du command to check the size of a directory in Linux? The answer is yes.The Linux du (Disk Usage) is a standard Unix/Linux command. It can be used to check the disk usage of files and directories on Linux system.If you need to get the size of a directory in Linux, use du -sh command. This will give you a total size for the directory, rather than listing the size of each individual file and subdirectory within it.This is the most efficient way to get the size of a directory in Linux.[root@howtouselinux]# du -sh /home/howtouselinux48K /home/howtouselinux[root@howtouselinux]# du -sh /etc/46M /etc/To find out the disk usage summary of a /home/howtouselinux directory tree and each of its subdirectories. Enter the command as:[root@howtouselinux]# du /home/howtouselinux40000 /home/howtouselinux/downloads4096 /home/howtouselinux/.mozilla/plugins4096 /home/howtouselinux/.mozilla/extensions[root@howtouselinux]# du -h /home/howtouselinux40K /home/howtouselinux/downloads4.0K /home/howtouselinux/.mozilla/plugins4.0K /home/howtouselinux/.mozilla/extensionsLet me summarize what we have got.Du is a command line utility for estimating file space usage. It can be used to find out not only the size of a given file, but also the size of a directory. For example, to check the size of the file “myfile.txt”, you would type:du -h myfile.txtIf you want du to check the sizes of all files and subdirectories within “mydir”, you can use the “-sh” option:du -sh mydirdu
