Optimizing Desktop Performance, Part III

Post date: May 31, 2005, 14:05 Category: Optimizing Views: 4888 Comments
Tutorial quote: For desktop and laptop users who want a fast-booting operating system, getting rid of services you do not need can appear to improve performance. Obviously, if you are new to Linux, though, you probably do not know which processes you can get rid of safely nor how to stop them and keep them from restarting at boot time.

Tuning up your IDE hard disks using hdparm

Post date: April 12, 2005, 18:04 Category: Optimizing Views: 3695 Comments
Tutorial quote: hdparm is a tool for altering various parameters associated with IDE drives (Not SCSI). This involves things like the block prefetch, the DMA/PIO modes,
and a number of other things.

I'm writing this mini-how-to to help people get more from their system. People often complain that Linux is a bit slow for them (which it can be) I haven't seen such a post recently, but I know on TechIMO at least we always used to be talking people through using hdparm.

Virtual Users And Domains With Postfix, Courier And MySQL (CentOS 5.1)

Post date: December 11, 2007, 09:12 Category: Installing Views: 4513 Comments
Tutorial quote: This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I will also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota (quota is not built into Postfix by default, I will show how to patch your Postfix appropriately). Passwords are stored in encrypted form in the database (most documents I found were dealing with plain text passwords which is a security risk). In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses.

Benchmarking Maildir Delivery on Linux Filesystems

Post date: April 12, 2005, 07:04 Category: Benchmarks Views: 3626 Comments
Tutorial quote: The goal of this set of benchmarks is to determine which of the leading Linux filesystems (ext2, ext3, ReiserFS, and XFS) offer the best performance when used for accepting maildir deliveries. The resulting system should be a good balance of delivery and retrieval performance under potentially high concurrent filesystem load.

Aggregating network interfaces

Post date: February 12, 2006, 07:02 Category: Network Views: 3497 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.
