eSignal Slow Download/Update

[nissan]

We have a dual-core powerful CPU with 3 GB RAM and 5 MBPS ADSL connection and the average speed of downloads from the internet is around 600-620 KBPS.

In spite of this powerful setup, we experience on our eSinal premier 2 types of real-time problems during the trading hours:

1. Slow updates of our intraday advanced charts ( 60 min and 10 min).
2. Slow (up to 30 seconds) switch from one symol to another on the charts.

Please note that when downloading the new eSignal version 10 the download speed is significantly reduced to around 30 KBPS!, as compared to the normal speed with other downloads of 600-620 KBPS. Since we do not perform this download very often but only whenever ther is a new version, this is not a real problem. But this indicates that we have a download/update problem with eSignal.

Can you please assisst us in resolving this problem and also let us know how can we change to a different eSignal server and refresh a chart.

Thank you very much for your comments and help.

One solution might be to have a Quote Window with the stocks you watch, then link the QW to a chart, at the start of the day, click on each entry in the QW, this will d/l the data for that stock. Then when you switch charts most of the data is already on your end.

This seems to work for me any way.

PS - you dont have to wait for each chart to perform the original update, just click on each symbol in the QW - one right after the other.

I would tend to question your download speed as being
the source of the problem. The reason is that I can put
my Reuters terminal, which is on a dedicated line, side
by side with eSignal and compare the data postings.
There is no difference that the human eye can detect.
However, my connection is 100Mbps and actual download
speed is 60 to 70Mbps over a fiber optic cable. True, you don't need all that speed to run a platform, but you might want to
check out this point for a solution.
Where I live we also had your type of problem when connection speeds were as slow as your speed is now.

Hope this information helps.

nissan,

As a point of comparasion I'm running the last rel 10 release.

Right now I'm running a old dell d600 laptop and have 20 forex charts running with automated strategies sending orders to IB. That IB TWS is huge Java application, and there are no delays at all in updating the charts.

When I switch symbols it takes maybe 5 seconds to load 120 days of 30 minute data.

I just downloaded the 30mb 10/31/07 ver 10 install file and it took about 90 seconds. I'm at home on the laptop using a Cable modem, which is about 300+kbs a second.

The only reason I'm pointing this out, is that it may help you resolve you problem more quickly by eliminating what is not causing the problem.

My guess is you can eliminate eSignal and your raw network bandwidth. Biut obviously there is a serious problem that has to be resolved.

If you are working at a firm with a network administrator you may want to see if there is firewall software that perhaps the eSignal ports need to be specified. In order for the esignal data to be processed quickly it cannot be filtered through fire wall code, looking for viruses etc.

Normally by default these products filter all network traffic unless specifically excluded. Which is the only thing I can suggest, hope it helps.
