Comment Read their report before attacking D.H.Brown (Score 1) 166
After reading some of the many comments on the D.H.Brown report on Linux, I found that noone bothered to actually read the report, just the poorly-written news article describing it. Here is what the report says:
1. Linux is great for: small file, print, and web servers; appliance-class systems; ISP's; computer nodes in Beowulf clusters.
2. Kernel 2.0.36 has poor SMP abilities.
3. Linux can only access *files* (not memory) up to 2 gigabites is size (Tru64 UNIX can access files up to 14TB in size)
4. Kernel 2.2 SMP should handle 8 processors, but there is no field evidence showing that Linux programs can properly handle multiple processors.
5. There is no redundant high availability (HA) clustering for Linux (even NT offers HA clusters with Microsoft cluster service). Beowulf does not help here because it was not designed to be redundant.
I could go on, but better that you read the executive summary posted for free at http://www.dhbrown.com, or buy the full report for $995.
