Subject Re: [Bug 60687] Make GUI more responsive when LoggerPanel gets a lot of events

Well, of course it is.

It could make sense to integrate "UI freeze profiling" right into JMeter
code so we could identify those freezes and tame them.
For instance: take an automatic thread dump in case UI thread spends more
than 500ms when processing a request (or something like that).

If we could capture UI latencies somehow, then we could plot them and
compare them (e.g. validate how different fixes impact/improve actual
JMeter use).

Back to the comparison, let me just cite the the conclusions for you (pay
attention to the second sentence of the first paragraph):

According to the measurements, replaceRange + append works faster than
setText except for the case when text is fully replaced. *In 100% replace
case setText is on par with replaceRange + append (the results are within
error bounds).*

For small appends there's a win in terms of response time and memory
