"I noticed that ******* quotes locked up shortly after the interest rate announcement yesterday while yours stayed stable." - Comment from Ron in Utah
"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
"Version has been working well for me and I appreciate that it is now a much tighter client to work with. I feel I can go to press with my own application and rely on a stable platform" - Comment from David in IA.

"IQFeed version 4 is a real screamer compared to anything else I have seen." - Comment from Tom
"DTN feed was the only feed that consistently matched Bloomberg feed for BID/ASK data verification work these past years......DTN feed is a must for my supply & demand based trading using Cumulative Delta" - Comment from Public Forum Post
"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
"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

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 client with Amibroker.

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

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.
