Linux Will Be Able To Boot 0.035 Seconds Faster With One Line Kernel Patch

Michael Larabel reports via Phoronix: Intel Linux engineer Colin Ian King discovered that if aligning the slab in the ACPI code via the "SLAB_HWCACHE_ALIGN" flag will offer a measurable improvement in memory performance and reducing the kernel boot time. Colin explained with this one line kernel patch: "Enabling SLAB_HWCACHE_ALIGN for the ACPI object caches improves boot speed in the ACPICA core for object allocation and free'ing especially in the AML parsing and execution phases in boot. Testing with 100 boots shows an average boot saving in acpi_init of ~35000 usecs compared to the unaligned version. Most of the ACPI objects being allocated and free'd are of very short life times in the critical paths for parsing and execution, so the extra memory used for alignment isn't too onerous."

Leveraging modprobe and lsmod for Effective Linux System Management

Introduction

Linux, renowned for its robustness and flexibility, owes much of its adaptability to kernel modules. These modules are critical components that extend the kernel’s capabilities without requiring a reboot, facilitating dynamic modification of the system’s functionality. In this article, we will delve into two pivotal tools—modprobe and lsmod—that are essential for managing these modules effectively. Understanding and utilizing these tools can greatly enhance system administration and customization.

Understanding Kernel Modules

Kernel modules are pieces of code that can be loaded into the kernel upon demand, providing additional functionality as required. They are essential for extending the system's capabilities, allowing hardware and software integration without altering the kernel's core structure. Common examples include device drivers for graphics cards and network interfaces, file system managers, and system utilities.

Modules streamline system performance and efficiency by only being loaded when needed. This modular nature ensures that the kernel remains lightweight and responsive, as unnecessary components are not loaded into the system memory permanently.

Exploring lsmod

lsmod is a simple yet powerful utility that lists all currently loaded kernel modules in the system. It provides insights into which modules are active, helping administrators understand the system's current state.

lsmod reads the contents from /proc/modules, which contains information about all the loaded modules. It displays the module name, size, and the count of instances that are using it, along with a list of any modules that depend on it.

Using lsmod: Practical Examples

To use lsmod, simply type lsmod in the terminal. The output will look something like this:

Module Size Used by nf_conntrack 139264 2 nf_nat,nf_conntrack_netlink iptable_filter 16384 1 ip_tables 28672 1 iptable_filter x_tables 40960 3 iptable_filter,ip_tables,ipt_REJECT

This output tells us which modules are loaded, their size, and their dependencies, providing a clear snapshot of the module landscape at any given moment.

Managing Kernel Modules with modprobe

modprobe is a more sophisticated tool compared to lsmod. It not only lists modules but also intelligently handles loading and unloading modules and their dependencies.

Introduction

Linux, an open source operating system, powers a vast array of devices from personal computers to servers and supercomputers. Its flexibility and efficiency have made it a popular choice among developers, system administrators, and tech enthusiasts. However, like any operating system, Linux requires performance optimization to ensure it operates at peak efficiency. This article delves into the intricacies of Linux performance optimization, offering detailed insights and practical tips to boost speed and efficiency.

Understanding Performance Metrics

To optimize Linux performance, understanding the key metrics is essential. These metrics provide insights into the system’s current state and help identify bottlenecks.

Key Performance Metrics to Monitor

1. CPU Usage: Indicates how much processing power is being used. High CPU usage may suggest the need for load balancing or process optimization.
2. Memory Usage: Tracks RAM consumption. Efficient memory usage is crucial for smooth operation.
3. Disk I/O: Measures the rate of data transfer to and from storage devices. High disk I/O can slow down the system.
4. Network I/O: Monitors data transfer rates over the network. Optimizing network I/O can prevent latency issues.

Tools for Measuring Performance

1. top: Provides a dynamic, real-time view of system processes and resource usage.
2. htop: An interactive process viewer, offering a more user-friendly interface compared to top.
3. iostat: Reports on CPU statistics and I/O statistics for devices and partitions.
4. vmstat: Provides an overview of system performance, including memory, processes, and I/O.
5. netstat: Displays network connections, routing tables, interface statistics, masquerade connections, and multicast memberships.

Setting Performance Baselines

Establishing performance baselines involves monitoring system metrics under normal operating conditions. These baselines help in identifying deviations and potential performance issues.

Optimizing CPU Performance

The CPU is the brain of any computer system. Optimizing CPU performance involves managing processes, tuning the kernel, and leveraging multithreading.
