What does the MS process do?

Every minute it uses up about 48% of CPU, which when combined with some applications running, pushes total CPU to nearly 100% for a few seconds.

In addition it is causing a massive DPC latency issue of about 23000 u/s.

I had some other DPC issues a couple of months ago and this process was not causing any DPC impact at that time - assuming it was part of Windows two months ago.

Can I disable the process - with what implication.

Has MS done something in their recent upgrades/patches that would cause this process to behave the way it is now?

I haven't noticed anything in this area. The Indexer will, well, index your files so you can search them.

Is your disk fragmented? Too many files? I have over 30,000 files in My Documents alone, plus 21,000 photos and don't see this kind of problem.

Thx for quick reply. I trade financial instruments via the internet. While researching this issue on Google (and before your reply came in), I closed the charts for my trading platform (I still have a data connection to the exchange and it is sending the trade signals - but I have closed the charts); and, guess what ....
that MS Search process is now consuming little CPU and the DPC latency has gone away.

So off to the trading software provider as there must be some incompatibility with their software and MS Search Indexer.

You can change what is indexed, I would just exclude the folders for the program you use.

Ragnor: You can change what is indexed, I would just exclude the folders for the program you use.

Can you point me in the direction of how I do that.

Much appreciated.

Using Vista.

Start
Control Panel
Indexing Options

Then select/deselect the drives/folders that you want to index.

Do whatever you want to do man.
