+1 on considering startup performance/memory usage. It looks like with Office 13 Microsoft has done more work in getting Office to startup faster (no benchmarks, just anecdotal experience).
+1 on the ability to do some kind of cross-compiling solution in parallel. +1 on gigabyte spreadsheets of floating point numbers. The competition kind of sucks in this regard... :-) On Thu, Jul 19, 2012 at 10:26 AM, Michael Meeks <michael.me...@suse.com> wrote: > > On Thu, 2012-07-19 at 16:04 +0200, Michael Stahl wrote: >> i'm saying it doesn't benefit from the "sophisticated" optimizations that >> vendor compilers like SunStudio or Intel do that speed up your BLAS >> stuff with gigabytes of floating point arrays by X times because office >> suites don't contain gigabytes of floating point arrays. > > So - Kohei has been working for years to turn Calc spreadsheets into > gigabyte arrays of floating point numbers - precisely to take advantage > of this sort of optimisation :-) > > Having said that, I totally agree, our problems are 95% algorithmic, > and fiddling with compiler optimiser settings is the last refuge of the > desperate man ;-) > > The thing that concerns me about gcc vs. MSVC++ is not the speed of > the > generated code, but it's size (which impacts startup performance, I/O > load, memory use etc.).
