I posted this in the DTN forum already, but maybe someone here has an idea.

I have a problem on my PC with the Windows Searchindex and the IQFeed client.

I had noticed that whenever I run my chart program (Sierracharts) the Windows Searchindex process starts to use an indecent amount of CPU time. In fact it uses more CPU time than Sierracharts.

Just starting the IQFeed diagnostic tool will have this effect, so Sierracharts itself is not involved.

I'm at a loss what setting for the Searchindex I have got to change to stop this.

I'm using Windows 7 Home Premium 64-bit and IQFeed 4.8.1.7.

Any ideas?

Many Thanks.

Problem has been solved. DTN support works even on Sunday afternoons so I got help from them.

Logging had been switched on for the IQ client. That made the client write a lot of text which the Searchindexer dutifully indexed.

It is switched on/off in the IQ diagnostics utility.
