I had to disable this. Just too many queries against MySQL.
With the mod enabled my server load averages (Dedicated Server, CentOS5, quad processor) were up in the 4's and 5's - the load peaked today at: 10.59 8.98 8.50
With this mod disabled, I'm now seeing consistent numbers like this: 0.38 0.33 0.53 with the same number of users as before -- this is more like "normal" for my hardware.
I turned on the slow query log in MySQL and it was filled with queries from this app. It's good, but the performance hit was killing my site. Users complaining about page load time, etc.
I'll look at the config and I'll see what I can change to be able to turn this back on.
