Problem Statement/Rationale

Compass average CPU usage is pretty high and the performance is degraded, making working with Compass sometimes too slow.

Please be sure to attach relevant logs with any sensitive data redacted.
How to retrieve logs for: Compass; Shell

Steps to Reproduce

• Open Activity Monitor
• Open Compass
• Connect to a cluster
• Take a look at the activity monitor, in the renderer process, you'll see an increased CPU usage (in my computer more than 30%)
• Now, collapse the side bar completely.
• In the acitivity monitor, eventually, the CPU usage will decrease to near 0.

Expected Results

The side-bar shouldn't have significant impact in CPU usage.

Actual Results

The side-bar, when open, consumes around 30% of the total CPU.
