Another good one from the Joom team.

Great plugin and good license for the price (I bought the lot). I use it multisite and it can be activated and configured separately per site, but is licensed for all domains at once… which is what I need.

I use it on Microsoft IIS and one should disable the IIS PHP caching as that tends to cause flakiness with some dynamic plugins.

I generally only use the caching and JS/CSS file grouping features in Speed of Light but all the other options are fun to tinker with as well.

Joom’s support has been very good and they regularly put out new releases with useful features. Good stuff.
