Note that there is an outlier in the no context property checking.  I've shown 
means with and without the largest/smallest dropped.

Time of translation (just before the call to lilypond-main and start of 
interpretation and just before the message "Interpreting..."), 10 runs with 
context property checking (in microseconds)
[261539, 261617, 261597, 261030, 265018, 260641, 282217, 262489, 262616, 265436]
mean: 264420.0
mean w/ outliers dropped: 262667.75

Time of translation, 10 runs with no context property checking (in microseconds)
[258837, 259777, 261231, 261915, 261306, 259702, 260661, 260903, 262827, 317991]
