Investigate Startup Times

GoogleCodeExporter commented 8 years ago


Especially Diagnosis and Plugin appear to have a higher than necessary startup 
time, maybe due to network lookups. Check why they take so long to initialize 
and fix that.

In Firefox 4 plugin startup time appears to be normal (e.g., when using :mouse: 
~1-2 seconds), while in Safari 5 and Chrome 9 the times are much longer (~5 
seconds).

Diagnosis startup time is caused by lookups for the EEG device. After 
re-enabling it in the tracking server, the startup time went back to normal 
again.

Example trace for the individual plugin startup times. Time to load all plugins 
is ~800 ms, a majority of the time appears go into the actual startup of the 
applet. Given that there appear to be no low-hanging solutions, I think we can 
postpose this issue to a later point ...

I further investigated the start-up times and located the top 10 hotspots.

Hmm, after fixing my local build/merge bug and testing the newest browserplugin 
version I couldn't find any  immediate hotspots running Simple Test.html.

Everything is up and running withing ~5s after applet loading. :)
