I dream of being able to tell the file system to be ready for a range of requests when they are first anticipated. In a extreme, I think about getting a NV store to load the pointers to the physical data, in cache and to not flush the cache until the context is released by the application thread. Going further into this reverie, anticipatory QoS for bandwidth is a personal desire. I'd even like to have a PCIe lane reserved, in my fascistic moments. Now I'm regretting my wordy comments above, because the explanation I wrote wasn't needed. But this dream I have to gain programmatic cooperation for data performance is surely not unique to me. Maybe twenty years ago it made perfect sense to leave the task of resources sharing to the operating system and subsystems, but now not only do many people have a high performance headroom to exploit, but the knowledge and experience of writing concurrent schedulers and load balances is far more commonplace, just by virtue of the needs presented by the crunch expansion of the Internet. The only point from my above comments that I think is under appreciated by the end users of software and worth approaching, is how much you can improve your software when you have a truly controlled environment. Talking straight through the operating system stack you can obtain uncoloured measurements from which you can build optimal performance applicable to all installations. I may dream, but I grew up with the worshipping of vendor benchmarks as my bete noir, and I have been set against waste created by supporting unrestrained variations, ever since. That makes sense for a commercial operating system, but the opportunity to work with completely homogeneous stacks is something that ought to be recognised for the value potential, by management. I'm convinced that this will be a critical commercial advantage for whoever first finds a solution that isn't a service only but customer deployable.
