I don¹t know if you tested this, but my results are exactly the opposite.
The first version is still faster.
const kReps = 1000000
dim t1, t2 as double
t1 = microseconds
dim s as string
for i as integer = 1 to kReps
s = "something"
s = s + " "
s = s + "else"
next
t1 = microseconds - t1
t2 = microseconds
dim output( 2 ) as string
for i as integer = 1 to kReps
output( 0 ) = "something"
output( 1 ) = " "
output( 2 ) = "else"
s = join( output, "" )
next
t2 = microseconds - t2
t1 = t1 / 1000000
t2 = t2 / 1000000
dim tally as string = format( t1, "#,0.000" ) + chr( 13 ) + format( t2,
"#,0.000" )
MsgBox tally
