Get More Out of Your Pipe with Apache and mod_gzip

Post date: April 14, 2005, 13:04 Category: Network Views: 2411 Comments
Tutorial quote: Some Web sites seem like they are designed to annoy and alienate visitors. Teeny tiny fixed fonts, weirdo fixed page widths, ad servers on Mars, and the content won't load until the ads do, and all kinds of dynamic jiggery-pokery that does everything but quickly deliver a nice, readable page.

Webmasters who are serious about running high-performance Web servers, and who want pleased and delighted visitors, have a great tool in Apache 1.3's mod_gzip. mod_gzip compresses pages on the fly, reducing their size considerably. Depending on the types of files served, you'll see size reductions ranging from 20%- 80%, and a nice increase in server efficiency. Nothing is needed on the client side, except sane modern Web browsers like Mozilla, Firefox, Opera, Galeon, and Konqueror. Mozilla, Firefox, and Opera are nice cross-platform browsers with all kinds of neat features, so don't be afraid to standardize on one of them.

Profiling in Linux Performance Tuning

Post date: December 18, 2005, 21:12 Category: Optimizing Views: 3415 Comments
Tutorial quote: This chapter covers several methods to measure execution time and real-time performance. The methods give different types of granularity, from the program’s complete execution time to how long each function in the program takes.

Aggregating network interfaces

Post date: February 12, 2006, 07:02 Category: Network Views: 2974 Comments
Tutorial quote: Using more than one hard drive to achieve better performance and fault tolerance is very common. Less well known is that it's also possible to aggregate more than one network interface into a single logical interface. In Linux, this is handled by the bonding driver. Benefits of doing this are much the same as the benefits of aggregating discs using RAID: if one device dies, your server carries on working and by using two devices in parallel, performance can be improved.

EVMS Howto for Gentoo Linux

Post date: April 15, 2005, 04:04 Category: Hardware Views: 4523 Comments
Tutorial quote: EVMS stands for Enterprise Volume Management System. It's a all-in-one utility written by IBM to manage disk partitions, logical volumes, software RAID and even filesystems.

It does everything from installing the partition table to mounting volumes, fscking and resizing them. It has a plugin mechanism which allow a user to extend EVMS with external drivers.

Network Performance Fine Tuning in openSUSE & SUSE

Post date: October 8, 2008, 23:10 Category: Network Views: 4224 Comments
Tutorial quote: openSUSE and SUSE Linux sets default values for some of the network related Kernel parameters. With Kernel 2.6 (default in recent releases of openSUSE & SuSE Linux), there are some fine tuning you can do to improve Network performance and get that extra out of your system.

Measuring the Performance of HTTP Web Servers using ApacheBench (ab)

Post date: January 24, 2010, 06:01 Category: Benchmarks Views: 4660 Comments
Tutorial quote: ApacheBench is a command line utility for measuring the performance of HTTP web servers, in particular the Apache HTTP Server. It was designed to give an idea of the performance that a given Apache installation can provide. In particular, it shows how many requests per second the server is capable of serving.

The PartImage Handbook

Post date: May 21, 2005, 15:05 Category: Software Views: 2507 Comments
Tutorial quote: - Partition Image is a Linux/UNIX partition imaging utility: it saves partitions formatted using the Ext2FS (the linux standard), ReiserFS (a new journaled and powerful file system), JFS IBM journaled file systems from AIX, NTFS (Windows NT File System), FAT16/32 (DOS & Windows file systems), or HPFS (OS/2 file system) file system formats to an image file. Only used blocks are copied. The image file can be compressed in the GZIP/BZIP2 formats to save disk space, and split into multiple files to be copied on removable media (ZIP for example), or burned on a CD-R ...

- This allows the user to save a full Linux/Windows system, with a single operation. When problems occur (viruses, crash, error, ...), you just have to restore, and after several minutes, all your system is restored (boot, files, ...), and fully working.

- This is very useful when installing the same software on many machines: just install one of them, create an image, and then restore the image on all other machines. After the first one, each subsequent installation can be made automaticaly, and only requires a few minutes.

Application optimization with compilers for Linux on POWER

Post date: May 23, 2005, 16:05 Category: Optimizing Views: 2715 Comments
Tutorial quote: The Linux on POWER platform offers more than one option to produce binary C/C++ code. In addition to supporting both 32- and 64-bit runtime environments simultaneously, Linux on POWER has two compiler collections. The GNU Compiler Collection, or GCC, is consistent with other Linux implementations with specific exceptions for the POWER architecture. GCC is the leading compiler for portability but also features a number of performance enhancements for optimizing code. The IBM XL C/C++ compiler for Linux on POWER is derived from the high performance compiler for AIX but uses the GNU linker and assembler to create ELF objects that are fully compatible with objects produced by GCC. This document provides side-by-side comparisons of how these two compilers are controlled, overviews of what the compilers are capable of, in terms of optimization, and tips for writing code that is more easily optimized with either of these compilers.

Debian RAID 1/5 system installer

Post date: May 28, 2005, 22:05 Category: Installing Views: 3087 Comments
Tutorial quote: Instructions for installing a very clean Debian GNU/Linux system that boots from RAID 1, and has RAID 1 or RAID 5 root and data filesystems.

The examples assume two identical harddrives, sda and sdb, on which after a small boot partition, 1 GB is used for swap, 25 GB is used for the root filesystem and everything else is for a big "data" partition that will hold non-system stuff.
