An example of the limits is that in my ''tests'' I used partitions and datasets of only several GiB, which is somewhat atypical nowadays, and I did so mostly to shorten the times taken for testing; and I wonder how much the numbers I get apply to partitions of several hundred GiB, which are becoming pretty common even for home users. evilninja> and it's a comparison at least. Yes, but then the question is ''of what?''. For example what do you think is being compared in the ''generic'' benchmark? Consider for example the relative size of the kernel source tree and that of your PC's memory, and that 'sync' does not have yet magical :-) powers. >> seems to me to be based on a rather original and imaginative >> approach (and overabundant faith in the magical powers of >> 'sync'), and its intepretation might be a challenge evilninja> are there any "certified" generic benchmarks out evilninja> there? Well, not really, because the so called ''methodology'' of running the benchmark matters _enormously_. The result arises out of the combination of benchmark, the way it is run, and the system. Doing precise benchmarks is impossible; even doing just somewhat/partially useful ones is quite difficult. Also, different usage patterns require very different benchmarks; consider viewing some of the links in my references note: http://WWW.sabi.co.UK/Notes/anno05-3rd.html#050911 Warning: some of those references are not as good as others, to speak euphemistically once more. ------------------------------------------------------- This SF.Net email is sponsored by: Power Architecture Resource Center: Free content, downloads, discussions, and more. http://solutions.newsforge.com/ibmarch.tmpl _______________________________________________ Jfs-discussion mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/jfs-discussion
