Well I wasn't thinking about Windows specifically. All of the products I work with, are cross-platform. That's why it sucks to be on Linux sometimes. Because Solaris X86 on the same hardware performs better, due to use of the Sun Studio compiler. .. > the election algorithms are all well known algorithms that you can > find in any thesis or computer scence textbook. > > the commit protocols are also well documented for all the known databases. > same goes for the failover algorithms. > > so the differentiator for the big boys are the implementation and nda > covered deals they have with the os vendor. > > what else? > > none. > > llvm will fix the optimization problem and the os support is already > solved in linux. > > so there. thats why im so gung ho over the closed source boys. I'm not so sure. Many of the things we're working on today have been known for 20 or 30 years. And yet, a lot of Free Software still sucks. Statements like the above, tend to gloss over implementation difficulties. Proofs of concept are easy. Ironing out all the tiny bugs is hard. I'll believe LLVM when I see it. Still, in the meantime, if you need the performance, you need to use Intel. Or Sun Studio. A compiler license is much cheaper than buying an 8-way server (instead of a 4-way server) because you're paying a performance tax. _________________________________________________ Philippine Linux Users' Group (PLUG) Mailing List [email protected] (#PLUG @ irc.free.net.ph) Read the Guidelines: http://linux.org.ph/lists Searchable Archives: http://archives.free.net.ph
