"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: Can only pass the trade Q message? (2 messages, Page 1 of 1)
jxz1995 -Interested User- Posts: 24 Joined: Jan 9, 2006	Posted: Mar 2, 2007 01:28 PM Msg. 1 of 2 Hi Support, We are experiencing high CPU usage of iqconnect too just like what the topic (http://forums.dtn.com/index.cfm?page=topic&topicID=1442&start=1) mentioned. We also noticed that the iqconnect using 95% for 10 seconds a couple of time in the busy periods which consuming around 50% of CPU. In the Q message, field #18 "Time" format HH:MMc. We are checking if the c is t or T and discard ohers. Is there any way to only receive trading Q message to reduce the iqconnect usage and thus to reduce the CPU usage? Besides we are suggesting somthing, is DTN doing some lab testing to come up with best pratice, like iqfeedY or socket (asyn calling receive buffer should be small or bigger) or using timer to receive. Thanks, Jim

It should be possible to add this as an option in a future release. We are certainly doing lab testing to make performance better in all aspects of the feed. The most recent release (4.2.0.7) is the best performing version of the 4.x series. If you have not made that update yet, I would certainly recommend it. Can you post the specs of the system you are currently using for IQFeed?
