Unix vs. Windows NT Comparison
Our Virtual Servers uses Unix BSDI operating systems for the majority of its servers because of the superior performance, flexibility and cost efficiency that Unix BSDI offers. The following is a comparison of the BSDI system to the Windows NT system.
EfficiencyUnix offers more performance at 1000MB than Windows NT offers at 2000MB. Unix is usually more proficient in the use of its memory, especially when dealing with network services. Because Unix requires less memory and processor time than Windows NT, a Unix based system has more memory and processor power for other computer functions.
PerformanceWith Unix and Windows NT running on standard PC's, Unix ran 27% faster than Windows NT when reading static HTML content, and with API generated content, Unix is between 47% and 197% faster. For CGI contents, Unix is 77% faster than Windows NT.
ReliabilityIndividuals and subsystems running on Windows NT crash far more frequently than a Unix system. Unix has been reliable for years due to its dependable software and technology.
Remote ManagementUnix was designed and implemented with remote management in mind. This enables system administrators to remotely perform management operations from another building or across the world. Windows NT is configured so that most of the administrative programs have to be run on the physical machine, without the ability to remotely control the machine.
Internet ServicesUnix has included things such as SMTP (Email), NNTP (News), Telnet, and DNS. All of these protocols and services were somehow forgotten by Windows NT. They can be covered up with third party products and Microsoft's own programs. However, none of these programs and products can compare to Unix in terms of flexibility and power.
Price ComparisonWith the Unix server's cost at approximately one fourth that of the Windows NT, it allows us to provide you with a more cost effective and powerful way to be on the Internet.
