<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 speedtest1.js; make -e emcc_opt='-O2' speedtest1.js</pre>
|
|
Then reload this page. -O2 seems to consistently produce the fastest results.

|
