I'm using the premium version of your plugin and I expirienced huge performance issues when stella is activated. (page loads in 8-10 seconds - without stella it loads in 1-2 seconds). This happens only on one of the sites where i'm using stella. All the others work fine.
Are there any known performance issues with this plugin?
Can i somehow tweak the perfomance?
I really like this plugin and wouldn't want to replace it because of performance issues!
