There are two views of memory, the one your process gets (virtual) and the one the kernel manages (real). The larger any page, the more difficult it's going to be to group (and keep it with) its neighbors, especially when your service is running on a system that also has to support others that by default allocate and write to way more memory than they actually end up using.
All of @MikkoRantalainen's examples are kernel memory usage due to being allocated by the kernel instead of being allocated in userspace (e.g., as inter-process shared memory). All structures needed by the kernel to administer a ring-3 process is kernel memory, not user memory due to who actually allocated it and who releases it (not who is the

The slabtop statistic header is tracking how many bytes of slabs are being used and it not a measure of physical memory. The 'Slab' field in the /proc/meminfo file Kernel memory is the memory used by the Windows kernel. It includes memory used by core components of Windows along with any device drivers. Typically, the 12 Mar 2021 Basic Concepts. Memory management is an important procedure in software development, including memory allocation, usage, and reclamation.

System memory in Linux is divided into two distinct space kernel space and userspace.Both the memory region has its own capabilities. This is a very important topic in OS, having a sound understanding of memory region helps in both debugging and writing the device driver and application programs. I have 3.10 kernel.

Kernel Memory (K): The Select Kernel memory dump.
Next, you’ll delve into the fairly complex topic of concurrency within the kernel, understand the issues it can cause, and learn how they can be addressed with various locking technologies (mutexes, spinlocks, atomic, and refcount operators). 2013-01-17 · Dynamic memory in kernel land is a little different from user land.

SunOS 5.4 kernel memory allocator, or ‘‘slab allo-cator,’’ in detail. (The name derives from one of the allocator’s main data structures, theslab. The name stuck within Sun because it was more distinc-tive than ‘‘object’’ or ‘‘cache.’’ Slabs will be dis-cussed in Section 3.2.) The termsobject, buffer, andchunkwill be
2018-04-06 · No memory is wasted due to fragmentation because each unique kernel data structure has an associated cache. Memory request can be satisfied quickly. The slab allocating scheme is particularly effective for managing when objects are frequently allocated or deallocated.

This is a very important topic in OS, having a sound understanding of memory region helps in both debugging and writing the device driver and application programs. I have 3.10 kernel. I am running some data processing job, need to first copy big (>5 GB) input files. The jobs were killed, because the system thought I used 5 GB memory from the file copying. 2018-04-06 · No memory is wasted due to fragmentation because each unique kernel data structure has an associated cache.
