Re[2]: [equinox-dev] About the benchmarks of OSGi

R3 are still compatible with R4. R4 added some new
class loading features but they are mostly in the more esoteric range
for large deployments that do not want to refactor their code.

R3 bundles are still more or less the preferred mode and run unchanged
on R4 frameworks.

Kind regards,

     Peter kriens

PR> � � � � - startup time
PR> � � � � - how many bundles can the system handle
PR> � � � � - service lookup time

PR> Hi all

PR> performance of the OSGi platform(such as Eclipse OSGi,SMF etc.)

PR> startup time, and so on. That is if I want to compare several OSGi
PR> platform’s performance, and optimize one of them, which aspects
PR> should I consider? Which aspects could demonstrate the performance
PR> of a OSGi platform?And if I want to do some optimization for OSGi
PR> platform,which aspects can I optimize?what is the Future
PR> directions?Any response will be appreciated, thanks very much.
