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