MonsterInsights Performance Addon GPL Features:

• Adjust site speed and sample rate for Google Analytics.
• When you are running a high-traffic site, you may hit the Google Analytics processing limit.
• To stay within that limit, MonsterInsights performance addon gives you the ability to make sample rate and site speed sample rate adjustments.
• This allows you to specify what percentage of users should be tracked, so you can stay within Google Analytics’ processing limit.
• The Site Speed Sample rate setting allows you to configure how often site speed tracking beacons will be sent which defaults to 1% of users automatically.
• In the future, our goal is to give you the ability to control complete site load analysis.
• We took the pain out of integrating Google Analytics with WordPress and made it easy.
