could be a memory issue (if lua is used, maybe the garbage collector)

should be no problem, but it can depend on what vatiant you use:

wls 1 : fast disk access accross os boundaries
wls 2 : faster disk access inside vm, much slower across

(so if you access files via /mnt/c then use a wls 1 machine)

but it is more likely that the slowdown relates to (your) macros or 
approach to the problem because there have been no changes in the engine 
that affect memory, node / token comsumption, or logging, but it can be 
you just cross some critital border now.
