Ahh a new version, is there a way to debug lag of page turns ?
With me its mostly high resolution pics being rendered to my devices resolution.
But Im interested any way.

Depends a bit on what you mean by debug, but either way the emulator would be the way to go unless there's a clear indication that there's something ARM-specific going on.

For LuaJIT, cf. https://www.freelists.org/post/luajit/LuaJIT-21-Profiler-released

For regular gdb stuff I like the Nemiver frontend, but anything goes. :P See https://github.com/koreader/koreader-base/wiki/Remote-debugging-with-gdbserver for doing it on-device.

I've done my profiling on crengine with cachegrind + KCachegrind for visualization. That resulted in some pretty significant performance gains (mostly thanks to @poire-z ).
