Hi,
Please review and merge fix[1] for public jira[2]. Did a load balance test
using 10 threads; issue is still seems to exist even though the fix[1]
improved the performance of the stream out (average server response time is
still growing).
IMO unified UI framework should not serve static type files(eg. images, js,
css ..etc); instead the container itself must be optimized to do the job.
Since we are using virtual paths here; simply escaping static file serving
from the framework would not be possible.
Virtual Path: {context}/public/{unit-name}/{resource-path}
Real Path: {context}/units/{unit-name}/public/{resources-path}
Virtual Path:
https://localhost:9443/iotserver/public/arduino/images/arduino.png
Real Path: https://localhost:9443/iotserver
/units/arduino/public/images/arduino.png
As per offline discussion, in order to solve this Manuranga is writing a
front layer in java for the UUI framework.
Thank you
