Unexpected Delay
Hello,
We have been using the LightStreamer Vivace for updating our clients. Recently we have noticed strange delays in peak periods. Using the Monitor Console, this information is acquired: At the peak time we had 1650 online users, 3000 connections, 1700 sessions and 6000 total subscribers.
Currently we have 2 web pages, the first page contains a stock watch, watch-list and total market details. The second is a market list with 400 instruments. Each instrument is updated using three message types. MaxItemFrequency of the above three messages is 1 second. In the second page, the messages are updated every one second and MaxBandWidth is 250.
Are these delays normal?
