Vista SP1 and file copy changes

The big news today (well, yesterday by the time this goes live) was that Windows Vista SP1 had released to manufacturing. Annoyingly enough, this doesn’t mean it’s available for public download yet, and end users will have to wait until in mid-March from Windows Update, or mid-April through Automatic Updates. I’ll keep my eye out for a validated copy from sources with access to the original MSDN files, because SP1 allegedly fixes some of the network copy issues I’ve been having recently.

As background, the network copy issues seem to involve Vista’s auto network tuning utility. I have a gigabit Ethernet connection between my Windows Home Server box and my primary Core2Quad system, and get about 40-50MB/s read speed without tweaking them using XP SP2 or Leopard clients. Vista, on the same Core2Quad and a 10K RPM Raptor drive, taps out at about 9MB/s and is often much slower than that, which is incredibly painful when working with 4+GB MKV files.

SP1 releases, at least with recent Microsoft products, have heralded new standards of stability and less crashiness. (SP2 really went above and beyond in fulfilling this role for XP, but it was an exception since it added additional security capabilities.)

The more interesting post of the day, though, is from Mark Russinovich’s blog in which he discusses the lower-level details of file copy operations. It’s definitely worth a read if you’re of the computer science mindset, and goes a long way to explaining some of the more intricate changes to Vista SP1.
