"I've been using IQFeed 4 in a multi-threaded situation for the last week or two on 2600 symbols or so with 100 simultaneous daily charts, and I have had 100% responsiveness." - Comment from Scott

"I'm satisfied with IQFeed. It's the most reliable and fastest quote feed I have ever used. Although I'm a resident in China, it's still very fast!" - Comment from Xiaofei

"I ran your IQFeed DDE vs. my broker vs. a level II window for some slow-moving options. I would see the level II quote change, then your feed update instantaneously. My broker's DDE, however, would take as much as 30 seconds to update. I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob

"With HUGE volume on AAPL and RIMM for 2 days, everyone in a trading room was whining about freezes, crashes and lag with *******, RealTick, TS and Cyber. InvestorRT with IQFeed was rock solid. I mean SOLID!" - Comment from Public IRC Chat

"Thank you so much - awesome feed, awesome service!" - Comment from Greg via Email

"I use IQ Feed, Great stuff as far as data analysis information, storage and retrieval is concerned." - Comment from Public Forum

"My broker in Davenport suggested I give you a try as he uses your service and says its the best." - Comment from Bill via RT Chat

"I just wanted to tell you what a fine job you have been doing. While *******, from what I hear, has been down and out, off and on, IQ feed has held like a champ this week." - Comment from Shirin

"I started a trial a few weeks back before the market went wild. DTN.IQ didn’t miss anything and beat my other provider. I decided to stay with you because of the great service through all the volatility." - Comment from Mike

"I just wanted to say how happy I am with your service. I was able to download the API docs last week and I was able to replicate Interactive Brokers historical bar queries and realtime bar queries over the weekend. That was about one of the fastest integrations that I've ever done and it works perfectly!!!!" - Comment from Jason via Email

Author	Topic: Is anyone else seeing large delays in streaming data today? (5 messages, Page 1 of 1)
Neil Brennan -Interested User- Posts: 38 Joined: Apr 13, 2007	Posted: Jul 25, 2007 10:09 AM Msg. 1 of 5 We have noticed what seem to be very large delays in the data from most servers tonight (and have reconnected a number of times looking for an up-to-date server). Particularly, we have noticed: 66.112.156.110 appeared to be 316 seconds behind at 10:54 66.112.156.229 appeared to be 485 seconds behind at 10:53 66.112.148.220 appeared to be 26 seconds behind at 10:48 We finally connected to 66.112.148.229 which seems to be up-to-date at the moment. Have any other users seen this behavior? Can anyone at IQFeed confirm/refute what we seem to be seeing? Regards, Neil Brennan

Do you track this yourselves? When we ring tech support they always seem surprised there is a delay, and ask us for the server details. Also, how is it that different servers seem to have such different delays? Regards, Neil Brennan

DTN_Jay_Froscheiser -VP, Product Operations- Posts: 1746 Joined: May 3, 2004 DTN IQFeed/DTN.IQ/DTN NxCore	Posted: Jul 26, 2007 08:24 AM Msg. 5 of 5 The delays being seeing are a factor of the market data being processed, the number of customers on the server, and the number of symbols being watched by those customers. This is what would cause the delays to be different depending which server you are connected to. If you happen to be on a server that has more users who watch more symbols, that server will be busier and possibly unable to keep up. We have installed an additional 8 servers last night (4 on each server farm). We hope this will help. We have also ordered an additional 20 servers. Because we are seeing more delays with the older code running on the x.x.156.x server farm, we are going to be turning off equity options to that farm today. If you need equity options (which you do, Greg7788), please contact customer support at 800-779-7299, on our website via RT Chat or via email. They will give you instructions on modifying your host file to force a connection to the new servers on the x.x.148.x server farm which will still have options data.
