Couple things to check in device manager.
Go to properties of the controller (may need to look at a particular channel on a controller). There will be an 'advanced settings' tab that should tell you if you are running DMA or not.
Go to properties of the Disk Drive itself. Look at the Policies tab. On an internal drive you should be optimized for performance with write chaching on disk enabled.
Check your event logs as well. Controllers will throw errors under event id 7,9,11. Disk/filesystem will throw events in the 5x range. As far as errors go for every one you see many have happened in the background. A delayed write failure for instance is the logging of the *retry* failure. The original won't get logged. So any errors seen are often the tip of the iceberg.
Indexing and whatnot should really not affect performance. I'm not 100% sure what else is going on in the background though. For me things started at an XP performance level then got snappier after about a day. I never went through any sluggish to non-sluggish transition.
