<p>Hi Sebastien, if you could help us update the benchmark, that
would be great!</p>
<p>Thanks</p>

<div dir="ltr">For the Spring Petclinic demo, I am not sure yet
about the reason for it to be an outlier, but I would suggest
to:

<div> - Use a more production-like arrangement by avoiding
creating the database schema at startup</div>

<div>Spring-boot Getting Started Demo should be also updated to
a more recent version and use the CDS/AOT cache friendly
unpacking feature.</div>

</div>
<div>I suggest we collaborate on that.<br>

Here are the results of {premain AOT} vs {JDK 25, no
CDS, no AOT}. Note that premain is generally much more
