Well, I tend to set Xmx / gclog before I launch it for the first time,
so I rarely see that popup.
AFAIK the default is something like Xmx750m:

Interesting. How/when do that happen ?
It's a popup ? does it often trigger ?

I'm sure some Xmx setting should be there.
Otherwise JVM might want to "consume all the existing memory", and it is
not something that is typically wanted.

If "out of memory" is the issue, then better strategy would be to display
relevant UI warning like "JMeter is might need more memory,
Xmx please adjust Xmx and restart".
As far as I know, IntelliJ IDEA follows that way.

Hi,
Unless there is a nogo, I'll commit this evening the patch that on test
creation add a Thread Group and a View Results tree.

I think this eases a bit first experience.

Regarding this thread, I still see unfortunately on stackoverflow and
twitter users running load test in gui mode and complaining about JMeter
not scaling.

This I think is an issue for Jmeter reputation, it's unfair but ignoring it
is not a good idea I think.

We discussed this in the past but didn't do anything yet:
- warning on start (i don't know if we discussed a threads threshold : 50
threads)
- limit View Results tree and table size in memory (patch exists but no
agreement)
- Have a dedicated Load Testing page on Home Page ? which would mention non
gui mode, heap settings , os tuning ...


I also wonder if we should not remove the default Xmx and Xms settings in
jmeter file. When using Java8 , default settings may be better as they
adapt to machine memory, but it can also be a problem...
