"Boy, probably spent a thousand hours trying to get ******* API to work right. And now two hours to have something running with IQFeed. Hmmm, guess I was pretty stupid to fight rather than switch all this time. And have gotten more customer service from you guys already than total from them… in five years." - Comment from Jim

"I would just like to say that IQFeed version 4 is running very well and I am very happy with its performance. I would also like to extend a big thanks for the fast and efficient help that I always receive. My questions and concerns are always addressed promptly. Way to go!" - Comment from Josh in CO.

"You have an excellent product !!!!!!" - Comment from Arely

"This beats the pants off CQG, I am definitely switching to the ProphetX 3.0!" - Comment from Stephen

"Thanks for the great product and support. During this week of high volume trading, my QuoteTracker + IQ Feed setup never missed a beat. Also, thanks for your swiftness in responding to data issues. I was on ******* for a few years before I made the switch over early this year, and wish I had done it a long time ago." - Comment from Ken

"Everything is working great ! Very impressive client. The news refreshes better and is more pertinent than the ******* feed I paid $ 100/month for. I Also like the charts a lot." - Comment from Leon

"Previously I was using *******. IQFeed is WAY more economical, and for my charting needs is just as good, if not better." - Comment from Public Forum Post

"You have an excellent feed. Very few spikes for Spot Forex." - Comment from Public Forum Post

"I cannot believe what a difference it makes trading with ProphetX!" - Comment from Bruce in Los Angeles

"Just a quick one to say I'm very impressed so far :) The documentation for developers is excellent and I've quickly managed to get an app written to do historical downloads. The system is very robust and pretty quick considering the extent of data that's available. The support guys have been very helpful too, in combination with the forums it's been plain sailing so far!" - Comment from Adam

Author	Topic: Windows Searchindex and IQFeed (3 messages, Page 1 of 1)
FGBL07 -Interested User- Posts: 41 Joined: Sep 8, 2011	Posted: Sep 23, 2012 08:15 AM Msg. 1 of 3 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.

You mention that just starting the diagnostics will cause this. Are you saying it increases the CPU without even running a test symbol in the diagnostics app? Can you tell if this happens only when the markets are open (I am looking at it on Sunday afternoon so that may be why I don't see any issues). One thing to check is that you don't have IQFeed logging turned on. You can turn this off in the diagnostics app by going to the logging tab. If for some reason Sierra Charts has logging turned on, this would cause the SearchIndex to continually index the file as it builds. I was able to see the search index using 2-3% CPU when I turned IQFeed logging on. Unless you are having problems, it is best to keep logging turned off as it will impact performance not only within IQFeed, but ancillary software such as the search indexer or virus scanners.

"..Are you saying it increases the CPU without even running a test symbol in the diagnostics app? " No, sorry, I was misleading on this. I had entered a test symbol (XG#) and started the test. I have set the log level now to "0 - no logging" and a first test shows that the Searchindexer no longer stresses the CPUs. Final test will be tomorrow during market hours. Many Thanks and have a nice Sunday.
