Maybe I wasn't clear I got better performance using -XX:MaxPermSize=128M so I wanted to try if increasing this value a bit would bring more improvements. 

Well I have created a folder with all the elements of the new selector so it was easy (thanks to winmerge) to do a little of back and forth starting with the 5.1.2 and then installing 5.2.2 on the same game instance (UP3.4 Patch 2 Hotfix23) then getting tired as I have two HDD on my machine  (basically a backup considering the 20+ years of life) I have on C drive the 5.1.2 and on the E drive a carbon copy of the instance with 5.2.2 so comparing is quicker and I avoid the deleting/overwriting always dangerous. There might be some variability induced by the different drives however results are quite consistent.

I also tested stock version (that I keep clean standing there just in case I need a fresh install) with the good old NoDVD Il-2fb.exe alone and then installing the selector and running the BlackDeath ntrk and some missions that used to cause me problems and noticed an improvement of performance. Not major but definitely an improvement. My conclusion is that the memory management being the static one of 5.1.2 or the dynamic of 5.2.2 has a positive impact. As you mentioned no significative difference between the two

Hm... okay.
If you don't mind, I'd like to call for an additional test, just to rule out things I haven't noticed yet.

First and foremost, the way to swap the BAT 4.3 selector against any former version is to exchange two folders and one file:

• "bin" folder
• "lib" folder
• "IL-2 Selector.exe" file

After changing files, run "IL-2 Selector.exe", check & save settings.

You need one fresh set of "bin" and "lib" folders from a game not being BAT 4.3, plus the corresponding "IL-2 Selector.exe" file (from whichever selector version you want to test against).
The second set is "bin" and "lib" folders and "IL-2 Selector.exe" from a fresh, untouched BAT 4.3 installation.
If you want to continue testing, I'd recommend you zip both sets and keep them in a safe place for further testing.

Now the test consists of running both the "old" and "new" Selector version with same settings, read: No Auto RAM adjustment on the new Selector, instead use static values like you did with the old one.
Comparative Test would then be to run the "new" Selector on Auto Settings, with Expert Mode enabled and the two magic lines:

Code: [Select]

-Xmx512M
-XX:MaxPermSize=128M...added in the "Additional JVM Parameters" box.
You can play around with these two values a bit, but as soon as you stay well within system limits, there should be no noticeable difference anymore.

I'm really curious as to whether there are any differences at all, and if so, which is the best and worst performer.

don't we need to swap the wrapper.dll as well? they seem to be different from one selector version to the other

Yeah sorry, one sentence was missing:
After changing files, run "IL-2 Selector.exe", check & save settings.

This will put the correct files in place.

I did everything as suggested comparing the selectors on the same UP3.4 instance on Win XP  and I am attaching three different Initlog corresponding to selector 5.1.2 with a static memory of 512 then same selector but in expert mode with -Xmx512M and -XX:MaxPermSize=128M then Selector 5.2.2 in expert mode with same parameters. The only odd thing that I can see is that is not clear what are the final setting for selector 5.1.2 in Expert mode. In terms of performances as to be expected there are no major differences but selector 5.1.2 in expert mode comes always slightly on top when running the BlackDeath track.
