that's does not happen to my knowledge, maybe formatting when setting up the disk, or disk is failing, Linux as far as I know does not have bottleneck of disk.

Vmstat should be checked as well to make sure your system is not requiring more memory than you have.<br />
What does the system do?<br />
Identifying your partitions with iostat 5 5<br />
Will point to where your reads and writes .......<br />
That may shed light on an issue.<br />
<br />
How your disks are setup, partitioned, arranged might ..........<br />
<br />
And the types in use<br />
Fdisk -l<br />
<br />
Do you sue LVM, software raid, etc.

no I don't use software RAID

try &quot;atop&quot; or &quot;htop&quot;, I use atop, better than top but you will have to find/install it for your distro, it shows loads of info, including processes/memory and cpu/disk in an easy to read screen and you can log over time.<br />
<br />
sar is another tool, use sar -d (might also need to be installed for your distro).

How one can find the bottleneck of a disk in Linux OS?

bottleneck of disk - performance quesiton

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.

Linux

The variety of Linux distributions creates myriad issues relating to configuration and operations when computers are networked, not the least of which is the use of various network management applications, some of which are included with specific distributions, while others are standalone applications.

Linux Networking

A Linux distribution is an operating system made as a software collection based on the Linux kernel and, often, on a package management system and are available for a variety of systems. A typical Linux distribution comprises a Linux kernel, GNU tools and libraries, additional software, documentation, a window system (the most common being the X Window System), a window manager, and a desktop environment. Most Linux systems are open-source software made available both as compiled binaries and in source code form, allowing modifications to the original software. Over three hundred distributions are in active development, including commercially backed distributions (such as Fedora, openSUSE and Ubuntu) and community-driven distributions (such as Debian, Slackware, Gentoo and Arch Linux).
