&gt; Well an IDE with less features is going to be faster than VS, that isn&#x27;t a question. Just see Sublime Text, insanely fast until you start adding extensions and it gradually gets slower and slower.<p>In principle, only a small proportion of features need to be actively consuming cycles. Most require no resources until invoked by the user.<p>Only a small proportion of <i>those</i> features are actively involved with drawing and so need to block the UI thread sometimes.<p>And only a small proportion of <i>those</i> features perform some essential drawing operation and so need to block the UI thread every frame.<p>So while a badly designed IDE with fewer features will outperform a badly designed IDE with many features, both will be trounced by a well-designed IDE with many features. It&#x27;s the design that matters.
