"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
"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

"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

For many months, IQFeed has been flawless. Every morning before market open I backfill roughly 500 symbols for the last 10 days or so and the process typically takes about 5-8 minutes.

Over the last few days (since Monday) it has been taking upwards of 20 minutes...

Anyone else experiencing slower backfill times? I'm using the 4.7.2.0 client with Amibroker.

Once the backfills are done and the symbols are in the cache, the realtime feeds seem to be fine.

Thanks,
David

Yes I have been noticing this as well. It takes more than twice as long as it used to which seems to match up with what you are seeing.

Please contact customer support first thing tomorrow with details of which IQFeed servers you are connecting to as well as what software you are using, what type of history data is being pulled, etc. We will dig into this to see what could be causing any changes in the performance you are seeing.
