    <p>I am testing different browsers on how do they read/write large amounts of data to/from local storage. Sample data is 1500 customer records with some set of data for everyone (first name, last name, some ids for their location, type, etc). Test application is built on GWT paltform.<br></p> <p>And what I noticed is that IE8, IE9, Chrome improved their performance in at least 30% after moving to loading data from local storage (rather than from web server). And only Firefox (5.0) is the one who worsened the results (around 30% slower). Remote web-server was used to bring some sort of reality into experiment. The difference between browsers is almost invisible on small data chunks (100-200 records) and the resulting time is also about to be the same. But large amounts reveal the problem.</p> <p>I found mentioning of this issue on mozilla support site - <a href="https://support.mozilla.com/en-US/questions/750266" rel="nofollow">https://support.mozilla.com/en-US/questions/750266</a> But still no solution or workaround there how to fix it.</p> <p>Javascript profiling shows that calls to function implemented in GWT StorageImpl.java class</p> <pre><code>function $key(storage, index){ return index &gt;= 0 &amp;&amp; index &lt; $wnd[storage].length ? $wnd[storage].key(index) : null; } </code></pre> <p>take the lion's share of time during execution. Which is actually storage.getItem(key) call in GWT.</p> <p>To avoid this frequent calls I would rather prefer a single call to translate storage contents to the map, for example, and it might help me to save time spent on Firefox's cache I/O operations (if any). But Storage interface ( <a href="http://dev.w3.org/html5/webstorage/#storage-0" rel="nofollow">http://dev.w3.org/html5/webstorage/#storage-0</a> ) contains only getItem() function to receive any contents from the storage.</p> <p>Any thoughts about how to force Firefox work <strong>faster</strong>?</p> <p>P.S. Maybe will be useful for someone: I found FF local storage contents using addon SQLite manager, and loading <em>webappstore.sqlite</em> database from the drop-down list of default built-in databases.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
