comment What causes average response time into the seconds for an SSD?
As I said above, I don't think that this is a software problem. Assuming I/O queuing is roughly FIFO, what would enqueue 90,000 requests in parallel? It's more likely to me that this is a system-software/driver or hardware failure of some sort.

comment What causes average response time into the seconds for an SSD?
This doesn't answer the question: If a task had to wait 9 seconds between issuing some I/O, and the disk can do 10,000 I/O requests per second, that means there are 90,000 other I/O requests ahead of this one. It seems unlikely that software would be written to have that request rate, because that wouldn't work at all on spinny disks. So, perhaps there's something wrong with the SSD, or the system, that causes artificial request rates or artificial latency? The main user of I/O is likely the background backup tool I use (CrashPlan.) But that shouldn't block all other I/O.

comment Applications like Chrome look blurry in windows 8.1
This is not new in Windows 8.1 -- display scaling has been with us since at least Vista. And a Surface and similar device really needs scaling, which worked just fine on 8.0. I think there must be more to this story, because 125% scaling in 8.0 was fine (and necessary); 8.1 is all fuzzy.

comment How can I set up a proxy for HTTP POST requests?
I really don't want to roll my own if I can avoid it. It seems WebSphere and WebLogic have these kinds of proxies as part of their SoA enterprise suites, so it seems like it can be done -- just not on a budget or technology stack I'm comfortable with :-)

comment Is there a high-performance local area “file sharing” protocol?
The 2 MB/s is probably because of iTunes, rather than the inherent set-up. That being said -- the answer to my question seems to be "no." Perhaps enough extensions can be added to NFS 4 to support change notifications and perhaps a Windows client could be written. But -- why hasn't anyone done this already? I want it all, right now, for free :-)

I agree that iTunes acts like a P.O.S. It's version 10.5, and it's still locking up the UI to scan a folder!

I agree that iTunes acts like a P.O.S. It's version 10.5, and it's still locking up the UI to scan a folder! That being said: you can solve this problem with judicious caching and pre-fetching. Which a high-performance remote file system would do.

Given how much faster CPUs are than long-haul wires, security doesn't need to be opposed to performance.
