Since jdk-arm (aur) is orphan and flagged out-of-date I switched to jre9-openjdk-headless.
Then I realized, jre9 is EOL too
So I switched to jre8-openjdk-headless, but with very bad performance for for i2p application
On jdk-arm and jre9-openjdk-headless I had no issues.
Looking into the details of PKGBUILD I found:
jre8-openjdk-headless
$this->bbcode_second_pass_code('', '
--with-jvm-variants=zero
')
jre9-openjdk-headless
$this->bbcode_second_pass_code('', '
if [[ $CARCH == "arm" ]]; then
_variants='zero'
else
_variants='server'
fi
')
Is this the key to my performance problem ?
I want to run i2p on a Pi3 / armv7l.
Thanks for any advise.
Edit:
someone adopted jdk-arm (aur) - so I'm fine with that and put this thread to closed.
If someone leave a comment about the zero/server question - I would be still very glad!
