For an intermediate state you could disallow line/page-breaking, doing
it all manually.
Below compiles in 4.1 seconds on my weak laptop
\version "2.19.81"
\layout {
\context {
\Score
\override NonMusicalPaperColumn.line-break-permission = ##f
\override NonMusicalPaperColumn.page-break-permission = ##f
}
}
global = {
\time 3/8
\key f \major
s4.*438
\bar "||"
\time 2/2
\set Timing.currentBarNumber = 1
s1*170
\bar "|."
}
main = {
\time 3/8
R8*3
\break
}
\new Staff <<
\main
\global
>>
