Outperform at "out of the box" testing. ;-) So, if I have a "desktop" distro like PCBSD, the only thing of relevance is putting up my own web server???? (Yes, the benchmark showed PCBSD seriously kicking butt with Apache on static pages.... but why would I care on a desktop OS?)
Personally, I found the whole thing lacking coherency and relevancy on just about anything. Don't get me wrong, I do like the fact that this was done. However, there are compiler differences (It was noted many times that CLANG was used and it may have been a detriment but it doesn't go into the how or why.) and other issues. There was a benchmark on PostGreSQL, but I didn't see any *BSD results? Transactions to a disk? Does this measure the "bundling" effect of the "groups of transactions" of ZFS? That's a whole lot less transactions that are sent to disk. (Does anyone know any place where this can be found? That is, how does the whole "bundling of disk I/O" go from writing to memory, locking those writes, then sending all the info in one shot to the disk? This helps: http://blog.delphix.com/ahl/2012/zfs-fundamentals-transaction-groups/ ) I was working at a company that had the intention of doing "electronic asset ingestion and tagging". Basically, take any thing moved to the front end web servers, copy it to disk, replicate it to other machines, etc... (maybe not in that order) The whole system was java based. This was 3 years ago. I believe I was using Debian V4 (it had just come out.... I don't recall the names etch, etc) and I took a single machine and rebuilt it 12 times: OpenSuSe with ext2, ext3, xfs. Debian with ext2, ext3, xfs. CentOS with ext2, ext3, xfs. FreeBSD 8.1 with ZFS, UFS2 w/ SU. Well, the numbers came in and this was all done on the same HP 180 1u server rebuilt that many times. I withheld the FBSD results as the development was done on Debian and people were "Linux inclined". The requisite was for 15000 tpm per machine for I/O. Linux could only get to 3500. People were pissed and they were looking at 5 years and $20m in time and development. That's when I put the FBSD results in front of them..... 75,200 tpm. Now, this was THEIR measurements and THEIR benchmarks (The Engineering team). The machine was doing nothing but running flat out on a horrible method of using directory structure to organize the asset tags... (yeah, ugly) However, ZFS almost didn't care compared to a traditional filesystem. So, what it comes down do is simple.... you can benchmark anything you want with various "authoritative" benchmarks, but in the end, your benchmark on your data set (aka real world in your world) is the only thing that matters. BTW, what happened in the situation I described? Despite, a huge cost savings and incredible performance.... "We have to use Debian as we never put any type of automation in place that would allow us to be able to move from one OS to another"... Yeah, I guess a Systems Architect (like me) is something that people tend to overlook. System automation to allow nimble transitions like that are totally overlooked. Benchmarks are "nice". However, tuning and understanding the underlying tech and what's it's good for is priceless. Knowing there are memory management issues, scheduling issues, certain types of I/O on certain FS that cause it to sing or sob, these are the things that will make someone invaluable. No one should be a tech bigot. The mantra should be: "The best tech for the situation". No one should care if it's BSD, Linux, or Windoze if it's what works best in the situation. P PS - When I see how many people are clueless about how much tech is ripped off from BSD to make other vendors' products just work and then they slap at BSD.... it's pretty bad. GPLv3? Thank you... there are so many people going to a "no GPL products in house" policy that there is a steady increase in BSD and ZFS. I can only hope GPLv4 becomes "If you use our stuff, we own all the machines and code that our stuff coexists on" :-) ________________________________ From: Adrian Chadd <[email protected]> To: O.
