<p dir="auto">Go to /browser/ in web browser and you will find that the following HTTP requests are constantly spinning:</p>
<p dir="auto">OPTIONS <a href="http://192.168.1.152:7474/db/data" rel="nofollow">http://192.168.1.152:7474/db/data</a> [HTTP/1.1 302 Found 0ms]<br>

<p dir="auto">It causes the browser to become unresponsive with regular freezes (in Ubuntu). Profiling the javascript code using firefox console shows that more than 50% of time is spent in: WCF__flushMessageQueue. Will enclose screenshot.</p>

<p dir="auto">On all systems I tried Neo4j, the web interface is causing high CPU usage, even if nothing is happen. On a Mac Mini 5.1 with OS X 10.9.3 in Safari this leads to 70-75% CPU usage, on a Windows 8 PC with AMD Phenom II X4 it reaches 35%. The same on my notebook with Intel Core 7. The java server process itself has not high usage.</p>
