571174c23eSstephan      <strong>Tips:</strong>
581174c23eSstephan      <ul>
591174c23eSstephan        <li>Control-click the flags to (de)select multiple flags.</li>
60*f5bf66c8Sstephan        <li>The <tt>--big-transactions</tt> flag is important for two
61*f5bf66c8Sstephan          of the bigger tests. Without it, those tests create a
62*f5bf66c8Sstephan          combined total of 140k implicit transactions, reducing their
63*f5bf66c8Sstephan          speed to an absolute crawl, especially when WASMFS is
64*f5bf66c8Sstephan          activated.
65*f5bf66c8Sstephan        </li>
661174c23eSstephan        <li>The easiest way to try different optimization levels is,
671174c23eSstephan          from this directory:
681174c23eSstephan          <pre>$ rm -f speedtest1.js; make -e emcc_opt='-O2' speedtest1.js</pre>
691174c23eSstephan          Then reload this page. -O2 seems to consistently produce the fastest results.
