<p>I know we haven't even had September's meeting yet, but I have a
possibility for October. A friend of mine will be in the States
for JavaOne and is trying to hit some local JUGs. He sent me an
email with some dates, and I've been slow to respond, so the only
one left is October 14, which is a Friday. I've included the
abstract and bio below<br>
</p>
<p><b>Ryan</b>, is the...event room (?) available at Starspace then?
Should I contact Clevyr to see if they could host? <br>
</p>
<p>I'd love to be able to have him present this. He gave this at
Devnexus, and while I didn't attend this session, I did get to
talk to the Azul contingent at their booth, and this looks
awesome. Would be a good one to share with the local Java peeps.</p>
<p>I am still trying to work out a time for Bruno Souza, from
Brazil, but I haven't heard any more from since my last email to
this group. If that works out, we may have <b>two</b> meetings in
October, but I'm ok with that, assuming we can work out the
logistics.<br>
</p>
<p>Anyone have any thoughts to share?<br>

What the CRaC - Superfast JVM startup<br>
<br>
<b>Abstract:</b><b><br>
</b>In a world where microservices are more and more a standard
architecture for Java based applications running in the cloud, the
JVM warmup time can become a limitation. Especially when you look
at spinning up new instances of an app as response to changes in
load, the warmup time can be a problem. Native images are one
solution to solve these problems because their statically ahead of
time compiled code simply doesn’t have to warmup and so has short
startup time. But even with the shorter startup time and smaller
footprint it doesn’t come without a drawback. The overall
performance might be slower because of the missing JIT
optimizations at runtime. There is a new OpenJDK project called
CRaC (Coordinated Restore at Checkpoint) which goal it is to
address the JVM warmup problem with a different approach. The idea
is to take a snapshot of the running JVM, store it in files and
restore the JVM at a later point in time (or even on another
machine).<br>
This session will give you a short overview of the CRaC project
and shows some results from a proof of concept implementation.<br>
