"Conventional wisdom says Linux is incredibly stable. Always skeptical, we decided to put that claim to the test over a 10-month period. In our test, we ran Caldera Systems OpenLinux, Red Hat Linux, and Windows NT Server 4.0 with Service Pack 3 on duplicate 100MHz Pentium systems with 64MB of memory. Ever since we first booted up our test systems in January, network requests have been sent to each server in parallel for standard Internet, file and print services. The results were quite revealing. Our NT server crashed an average of once every six weeks. Each failure took roughly 30 minutes to fix. That's not so bad, until you consider that neither Linux server ever went down. This test, coupled with our technical staff's extensive Linux and NT experience, leads us to believe that Linux truly is more stable than NT on uniprocessor servers."
