My site has been slowing to a crawl at times, even with only 20 members online. During some of these slow periods, the average page load time exceeds 70 seconds. Opening a comment window can take 30 seconds. Posting sometimes takes so long (with a long delay after the spinning icon stops) that our members end up posting multiple times because they think it didn't work. Also, some users are not able to log in because it times out.
Our server set up has been optimized by the UNA team and our host. They're a solid host, and our server specs exceed those of UNA's Cloud16. We chose the specs we did, based on UNA's recommendations for a site with 150 online users / 100,000 members, but we're still seeing issues with only 20 online. We've checked our server logs for issues and monitored server load, and it rarely gets very high, even when users are experiencing the slowdown.
This occurs at seemingly random times during the day and is causing a lot of our members to be frustrated. Many have left because of it.
Has anyone dealt with this or resolved a similar issue or have ideas?
This is on UNA 9.0.0, not 10.
