          <ul>
            <li><strong>Measure Full Render Time</strong> - full render time measurement (recalc style/layout/paint/composition/etc).</li>
            <li><strong>Preserve State</strong> - preserves internal state when moving DOM nodes.</li>
            <li><strong>DOM Recycling</strong> - DOM recycling is enabled, instead of creating new DOM nodes
              on each update, it reuses them.</li>
            <li><strong>sCU Optimization</strong> - <code>shouldComponentUpdate</code> optimization is enabled.</li>
            <li><strong>Spec Tests</strong> - Internal specification tests.</li>
          </ul>
          <h4>Notes:</h4>
          <ul>
            <li>Time is measured in microseconds.</li>
            <li><u>JS Init Time</u> is hugely depends on scripts downloading time, run benchmark multiple times to make sure
              that scripts are available in a browser cache.</li>
            <li>Don't use <u>Overall Tests Time</u> row to make any conclusions, like library X is N times faster than
              library Y. This row is used by library developers to easily check if there is some regression.</li>
            <li>When <u>sCU Optimization</u> is disabled, <code>no_change</code> test cases will show pure
              render/diff overhead.</li>
            <li>Implementations that doesn't <u>Preserve State</u> when updating children can get a way much better results
              than those who preserve state in some test cases when <u>Measure Full Render Time</u> is enabled because they
              don't trigger long-running recalc style/layout. But most of the time it isn't important because
              implementations that doesn't properly rearrange nodes will be slower in other important use cases.</li>
            <li>Implementations with some form of <u>DOM recycling</u> will have a way much better results in <code>render</code>
              use cases. For example, Imba library algorithm for diffing is hugely depends on this behavior, so it is
              hard to properly benchmark <code>render</code> and <code>insert</code> test cases. Implementations with
              this form of DOM recycling are actually taking exactly the same DOM nodes from pool, so they don't need to
              update anything, and they just insert prerendered nodes.</li>
          </ul>

          <ul>

              be executed before any spec/scu/recycling tests, so it may be considered as a "cold" run.</li>
            <li><code>table/[100,4]/render</code> - render table with 100 rows and 1+4 columns.</li>
            <li><code>table/[100,4]/removeAll</code> - remove all rows from a table with 100 rows and 1+4 columns.</li>
            <li><code>table/[100,4]/sort/0</code> - sort rows in alphabetic order by first column.</li>
            <li><code>table/[100,4]/filter/32</code> - remove each 32th row.</li>
            <li><code>table/[100,4]/activate/32</code> - activate each 32th row (adds "active" class to each activated row).</li>
            <li><code>anim/100/32</code> - update style in each 32th div.</li>
            <li><code>tree/[50,10]/render</code> - render tree with 50 top-level nodes with 10 nodes in each top-level node.</li>

            <li><strong>Measure Full Render Time</strong> - full render time measurement (recalc style/layout/paint/composition/etc).</li>
            <li><strong>Preserve State</strong> - preserves internal state when moving DOM nodes.</li>
            <li><strong>DOM Recycling</strong> - DOM recycling is enabled, instead of creating new DOM nodes
              on each update, it reuses them.</li>
            <li><strong>sCU Optimization</strong> - <code>shouldComponentUpdate</code> optimization is enabled.</li>
            <li><strong>Spec Tests</strong> - Internal specification tests.</li>
          </ul>
          <h4>Notes:</h4>
          <ul>
            <li>Time is measured in microseconds.</li>
            <li><u>JS Init Time</u> is hugely depends on scripts downloading time, run benchmark multiple times to make sure
              that scripts are available in a browser cache.</li>
            <li>Don't use <u>Overall Tests Time</u> row to make any conclusions, like library X is N times faster than
              library Y. This row is used by library developers to easily check if there is some regression.</li>
            <li>When <u>sCU Optimization</u> is disabled, <code>no_change</code> test cases will show pure
              render/diff overhead.</li>
            <li>Implementations that doesn't <u>Preserve State</u> when updating children can get a way much better results
              than those who preserve state in some test cases when <u>Measure Full Render Time</u> is enabled because they
              don't trigger long-running recalc style/layout. But most of the time it isn't important because
              implementations that doesn't properly rearrange nodes will be slower in other important use cases.</li>
            <li>Implementations with some form of <u>DOM recycling</u> will have a way much better results in <code>render</code>
              use cases. For example, Imba library algorithm for diffing is hugely depends on this behavior, so it is
              hard to properly benchmark <code>render</code> and <code>insert</code> test cases. Implementations with
              this form of DOM recycling are actually taking exactly the same DOM nodes from pool, so they don't need to
              update anything, and they just insert prerendered nodes.</li>
          </ul>
          <h4>Tests:</h4>
          <ul>
            <li><u>JS Init Time</u> - js initialization time.</li>
            <li><u>First Render Time</u> - time to execute <code>table/[100,4]/render</code> for the first time, it will
              be executed before any spec/scu/recycling tests, so it may be considered as a "cold" run.</li>
            <li><code>table/[100,4]/render</code> - render table with 100 rows and 1+4 columns.</li>
            <li><code>table/[100,4]/removeAll</code> - remove all rows from a table with 100 rows and 1+4 columns.</li>
            <li><code>table/[100,4]/sort/0</code> - sort rows in alphabetic order by first column.</li>
            <li><code>table/[100,4]/filter/32</code> - remove each 32th row.</li>
            <li><code>table/[100,4]/activate/32</code> - activate each 32th row (adds "active" class to each activated row).</li>
            <li><code>anim/100/32</code> - update style in each 32th div.</li>
            <li><code>tree/[50,10]/render</code> - render tree with 50 top-level nodes with 10 nodes in each top-level node.</li>
            <li><code>tree/[50,10]/removeAll</code> - remove all top-level nodes.</li>
            <li><code>tree/[50,10]/[reverse]</code> - reverse all top-level nodes.</li>
            <li><code>tree/[50,10]/[insertFirst(1)]</code> - insert one top-level node at the beginning.</li>
            <li><code>tree/[50,10]/[insertLast(1)]</code> - insert one top-level node at the end.</li>
            <li><code>tree/[50,10]/[removeFirst(1)]</code> - remove one top-level node at the beginning.</li>
            <li><code>tree/[50,10]/[removeLast(1)]</code> - remove one top-level node at the end.</li>
            <li><code>tree/[50,10]/[moveFromEndToStart(1)]</code> - move one top-level node from the end to the beginning.</li>
            <li><code>tree/[50,10]/[moveFromStartToEnd(1)]</code> - move one top-level node from the beginning to the end.</li>
            <li><code>tree/[50,10]/[*_worst_case]</code> - special test cases that should trigger worst case scenarios for
              children reconciliation algorithms in different libraries.</li>
            <li><code>tree/[10,10,10,10]/no_change</code> - trigger update without any changes.</li>
