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?
