Performance tuning, best practices

we have a system where we serve from a host process around 200 clients connected via webSockets (Jetty). The core process is running on a dedicated Windows 2012 server with 16 GByte RAM and 8 processor cores.  What is strange for us is that max 20% of the cpu resources are used and the IO subsystem is at maximum 30% of activity under heavy load but database queries are let's say not at the speed we would expect. We have currently 20.000.000 objects in the database, our configuration settings are: ...     <quota directories="5" files="20" disk-space="5mb" />    </dir> ...

Eclipse plugin problem (using ObjectDB as a separate bundle)

Hello support, I have seen multiple attempts to correct similar errors as in the title above - the latest in the 2.2.8.01 release of objectDb.

significant performance decrease

we are using objected in embedded mode (on OS X and WINDOWS). The database increased now to around 400000 entities of one class (database file size around 1.5 GByte). The response time of standard queries increased with this database size to an unacceptable rate (several seconds compared to around 30% when the number of entities was just half of the current). We tried to optimize the cache settings, current objectdb.conf is: <!-- ObjectDB Configuration --> <objectdb> ... > <quota directories = "5" files = "20" disk-space = "5mb" /> ...

JBoss 7.1 and EAP 6 support

I understand that keeping up with a new version can be difficult. Having said that, JBoss 7.1.1 Final was released in early March and Enterprise Application Platform (EAP) 6, the fully supported version by RedHat which is based on 7.1, has been released recently. I would really like to use ObjectDB since I believe that I will need the performance gains you show. Is there a plan to support this version of JBoss? I would also like to ask when but I know timeframes are not really known in advance, let me just state that my project will need to go live in about 4 weeks. #1 2012-07-15 20:44 I understand that keeping up with a new version can be difficult.
