java execution time

[Duss Pirmin]

Hello Genodians

I have a JAVA application that I execute on request by starting it in a
sub init. When debugging why it takes about 6 seconds on x86_64 to
handle a request I made the discovery that when Java is included via
`import_from_depot` in the runs script, that the execution time goes
down to under one second. But when it is included via the depot
mechanism, the execution is slow.

In my tries to speed up I modified the JDK package to take the content
of the `classes.tar` from a ram_fs where I extracted the file to. But
this did not improve the execution time in a significant way. I did this
tests on sculpt.

Has someone an idea what causes this increases in execution time and if
there could be a way to reduce it?

Regards, Pirmin
