Hi Jozef, Stuart, and Weld-devs,<br>
<br>
In Forge 2 we are using Weld extensively, and one of the things we do is<br>
start up many instances simultaneously.<br>
<br>
We may have anywhere from one to one-hundred or more weld instances.<br>
Currently we have only seen around 10-12 instances, and performance is<br>
"Okay", but in theory, we could see hundreds of instances, at which<br>
point, performance starts to be a concern. We're working around this<br>
problem by disabling CDI support on some internal addons, but... it's<br>
not really reasonable to expect that everyone will do this.<br>
<br>
Which means... we need to figure out how to shave as much time off the<br>
bootstrap as possible. Currently each weld instance takes anywhere from<br>
80ms to 450ms to start (not really sure why such variation yet,) and<br>
we'd hopefully like to get that down even lower, around 10-20ms.<br>
Classloading time only would be optimal, but obviously difficult to achieve.<br>
<br>
<br>
How can we get the most speed out of Weld? Most of our deployments have<br>
only ~15 bean classes at most. It seems like a lot of time (~30-40%) is<br>
being spent in the Google concurrent collections.<br>
<br>
(Screenshot attached.)<br>
<br>
Thanks,<br>
<br>
