>So Windows Server could match Linux for performance 6 years ago as well as a decade ago. Your point is?
Ok, I did not even read that when I saw the date apparently, you did not either ... ;-)
As much as I hate "benchmarks", because in theory they are the same as in practice and in practice they ain't, even this benchmark gives Suse/Oracle faster than MS SQL Server, pretty close, though.
The second is an old version of MaxDB vs MS SQL Server (where SQL Server wins, tada - you found a benchmark, impressed) and seeing how SAP has improved performance of that DB over the last years, I doubt you would see the same results. You will note that the Database Request time is 6 times better on Linux/MaxDB than Windows/MS SQL Server - so clearly optimization was needed in MaxDB.
Why am I claiming Linux beats Windows all the time ? Because in Windows you have a bunch of unused subsystems and other crap like ui's running, in Linux, you have exactly what you need running. So, there is absolutely no way Windows can outperform Linux - MS have now realized this and you get a headless Windows server now, but, looking at the HD footprint (arguably not very reliable metric), they have only removed ui, not the unused subsystems - I have not tested this, but I am pretty confident. In the other SAP benchmarks, UNIX wins because of the HW, that is why I said on same hw. I could not see UNIX/Windows/Linux performance results with identical hw - might need to export to csv and have a closer look.
Listen, I work on a piece of software that is pretty database intensive and we support a wide array of db flavors and I can tell you, I see the high load tests we run nightly every morning, and they do not look good for MS SQL Server. MaxDB now performs much better, which was not the case some years ago, you are correct ... that is why I am appalled that so many shops run MS SQL Server instead of more capable OS/db combinations ... especially considering the price.
I will stop arguing here because it is in vain, window cleaners have no clue and think they know better - fine, so be it.
As for the other bloke with his 300 quid, lol, you really mean I can choose the sql ? This article says which queries I can choose to prevent you from using in-mem database and you think you can still beat my in-memory Sybase/SLES, seriously ? 300? My rate for two hours work ...
