JVM 1.8 on D4.5.3 any performance differences?
I noticed in the SP3 notes that they recommend switching to java 1.8 for
Designer.
on Winders was a literal piece of cake, and I am running it now.
Anyone seen performance differences with Java 8? My theory is that a
lot of the Designer lags are garbage collection based. Presumably this
is a hot topic in the Java world to be improved on in major releases.
(But I may be naive. Or did I mean Evian? backwards/forwards, what
difference does it make anyway?)

Subscriber channel, publisher channel, who cares. It's all the same.
No I haven't seen any difference with 1.8 so far.

If you had looked at the JRE shipped with a fresh install of Designer
4.5.2 you would see that it already ships with Java 1.8 r60
Maybe the JRE is older if you did auto-updates each time from Designer
4.5.0 onwards (if this is even possible).
The recommendation here is to update to Java 1.8 r66 and I'm guessing
that this is primarily for secuirty fixes.

This is a common perception, but I have played with various GC options
and there are some workable combinations, but again this varies greatly
from OS to OS and Designer version. I need to do more testing with
Designer 4.5.x as a lot of the older tweaks don't work well against it.
Pure performance is not always the primary goal.
For example, we needed a set of options that performed really well on
Designer in a memory and resource constrained environment (Windows,
running multiple instances of Designer on Citrix/terminal services).
