We have built a system with WordPress, and are using the Quick Chat plugin ([login to view URL]) to host live Q&A sessions for our subscribers. When more than 6 or 7 logged in users are using the chat system, it begins to slow down, until the site becomes unresponsive. The hosting company have said it is due to most of the load and slowness coming from inefficient sql queries. It is being hosted on a dedicated VPS.
We are looking for someone to resolve the issue.

Hey Hi there. Maybe a bit of SQL tweak is required which i am proficient at. Also i'd be looking at the logs to investigate thoroughly (if you can provide access to server). Thanks
