<p>I found HHVM to be fast, but not much faster than using an opcode
cache, which I think is simpler to set up and easier to keep
updated.<br>

that speeds up PHP processing quite a lot, then you are probably
database bound and need to look at indexing - oh and stick the
database on an SSD rather than rotating disk and it will go quite a
bit faster.<br>

</div>
<div>To HHVM:</div>
<div><b>The most important one at first</b>: Every feature of
Vtiger/PDFMaker/EmailMaker works! I never found one function I
cannot use. And I/we use it in production for a huge client,
which would directly complain about a problem.</div>
<div>Facebook take a look to be more compatibly a little bit. (Not
generally all PHP is compatible, but nothing within vtiger)</div>
<div><br>
</div>
<div>Maybe you don't trust my benchmark and I couldn't believe it
myself. Maybe in production environment I had some special MySQL
Improvements.�</div>
<div><br>
</div>
<div>But in production I use mysql replication, which gave a very
little decreased performance.</div>
<div>I have two similar systems with ~200 000 Records in
crmentity. (I must say VtigerCRM 6.2)</div>
<div><br>
</div>
<div>1 Testing system - On PHP 5.6:</div>
<div>1 Open the Invoice overview with 30 records and the loading
time is ~1.5 sec.</div>
<div><br>
</div>
<div>1 Production - On HHVM:</div>
<div>I open the Overview of Invoices with 50 Records and the
loading time is 475ms.</div>
<div><br>
</div>
<div>An explanation could be, like Alan means, Vtiger heavily
works inside to_html function. HHVM extremely optimize often
used functions.</div>
<div>But I never try to figure out, why it is so fast.</div>
