Karaf Container 4.0.x / minimum configuration

Hi,
I am looking for the minimum recommanded configuration (HW requirements:
Flash and RAM) 
for Karaf Container 4.0.x .
In the Karaf User's Guide, there is that information:
50 MB of free disk space for the Apache Karaf binary distribution.
Does it exist others recommandations?
I ask that question cause we use Karaf Container 4.0.x and JDK 1.8,
and we noticed some slow-down in the execution program and a very high cpu
occupancy.
If you have some clues to check that the configuration is correctly set,
it is interesting me.

Thanks in advance for your help,
JL Jordan

If you don't need the dynamism of OSGi / Karaf, you could build your custom
static distribution.  It would trim down the requirements because the
feature resolution would not need to happen and because bundles can be
installed directly from the repository without being copied to the cache
folder.

Hi,
do you use the OpenJDK or Oracle Java?
On ARM the Oracle JVM works much better (performace) then the OpenJDK
-- at the time I tested it.

Best regards,
Markus

Hi JB,

Thanks for your answer.
We use Debian 8 (Jessie) with a kernel part based on NXP Linux BSP iMx
version 4.1.15_1.2.0
and user part is the base system Debian.
We have 1GB RAM and 4 GB Flash and our software is executed on 16GB Micro-SD
card.
Following our installation procedure, first we install Karaf and launch it
without features.
It is in the next step that the features are installed.
But in the first step, after the Karaf installation, 
if we execute a command through the Karaf console,
it takes 1 minute almost. 
We checked by a top command that karaf process has a 100% cpu occupancy. 
We checked that we have not the issue if we install Karaf on a Virtual Box.

Regards,
Jean-Luc Jordan

Hi JL,

Karaf 4.0.x requires:
- Java 8
- 512M RAM
- 50MB free filesystem space

What do you have installed on Karaf (additional feature) ? On which OS ?

Regards
JB
