Limit the number of participants in a meeting to the essential ones. Each participant will increase the total load (Bandwidth & CPU) on all other hosts and speakers. Shoflo Studio works best with 2-5 participants.
Limit the number of hosts logged into the same Studio instance. Shoflo Studio works with multiple hosts but each one also introduces variables and loads.
The host’s computer should be isolated from any other loads. i.e. it should be running the browser and studio but nothing else.
Hardwire your computers to your network for the best possible internet connection.

An improved camera can make a big difference but before going out and purchasing a new one, do you have an old DSLR in the closet? consider using that.
A Capture Card will allow you to use any HDMI video source as a 'camera' so if you are using an old DSLR as a webcam or trying to share a gaming console's output... A capture card could be a useful tool.
Audio is an important part of every stream and an upgraded microphone can go a long way toward improving your audience's experience. Even the microphone built into your headsets can oftentimes be an improvement over the one built into your laptop.
Use headphones or a headset whenever possible, This improves the overall sound by removing the other audio elements from being picked up by your mic.
Try to use a secondary monitor especially if you are sharing your screen.
Environment
Give your background some thought, reduce distracting elements, and try to frame yourself within the shot.
Make sure you center yourself on your video, Studio auto-crops your video in some layouts so being on the outer edges will not look as good.
Adequate lighting is key to looking good on video. Ring lights are a good option if your room is not well lit but try to avoid overhead lights as those can cause unflattering shadows.
Try to isolate yourself to avoid external noises or other visual distractions.
