Have you tried any of the windows based password recovery tools?

I'm not really worried about windows based ones. People that are already using rarcrack claim speeds 200/s and some seems to claim even 1200/s. Does it have to do with file size maybe? File type? the fact that its booting from cd?

For those not familiar with Backtrack it is a version of linux for information security professionals. I am running from cd and everything loads correctly. I am trying to use rarcrack to audit our password policy and I am finding that performance is ridiculously slow (around 5 passwords/second) and other seem to claim 100s /second. <br />
<br />
I am aware that some material around this is against EE policy and I support that so my question is only directed at the OS asking why is the performance so slow? Eventhough I am booting from a CD I thought it uses the harddrive or ram to store temporary files for faster performance.<br />

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).

Linux Distributions

The Linux operating system, in all its flavors, has its own share of security flaws that allow intrusions, but there are various mechanisms by which these flaws can be removed, generally divided into two parts: authentication and access control. Authentication is responsible for ensuring that a user requesting access to the system is really the user with the account, while access control is responsible for controlling which resources each account has access to and what kind of access is permitted.

Linux Security

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.
