Novell vs. Microsoft - Benchmarks
I Just found this article in The Register which talks about KeyLabs comparing Novell's NDS eDirectory vs. MS's Windows 2000 Active Directory. Here is the KeyLabs benchmark report (requires PDF reader) and here is another link to Novell's eDirectory Benchmark. (also, here is what Novell says about it). I'm sure this is only round 1 and we will surely see some other reports...
On the Novell page, comparing reliability..
The scale is between 80 and 100 percent. The low 90 that MS scores just PALES in comparision to that full-height 100.
Of course, ~10% downtime is an extremely significant number if you're talking mission critital.. But still, it's not the 50% that it looks like.
Lies.
Damn lies.
Statistics.
Benchmarks.

As a longtime /. reader, however, I say "before we slam anyone (Microsoft, Novell, the test lab, etc.) let folks familiar with Win2k post information about the test parameters to show any biases toward Novell in how the test was set up -- a la the accusations against Mindcraft which IIRC were mostly proven to be false in the 3rd run of that particular benchmark.
What I like about this particular study as published is that they were very up front about the tuning parameters, such as they are. My hope would be that Microsoft will respond with their "ideal tuning parameters", and then the benchmark can be run again, with the results posted here.
...Open Source isn't the only answer -- but it's almost always a better value than the alternatives...
As a Nescape employee, I can't help but ask why Netscape Directory Server wasn't included in these tests? Since Netscape Directory Server has > than 70% market share in the LDAP market, I don't understand how it wouldn't included in a major benchmark.
I don't know the particulars of these benchmarks, but Netscape Directory Server has been benchmarked at speeds almost an order of magnitude higher. Of course, I don't know if that's comparing apples to apples. But I'd like to know!
