That helped a lot, I disable GC and inlined as you suggested and 
the time is now:

Time (s): 8.754

However, with R's data.table package gives us:

system.time(x <- fread("Acquisition_2009Q2.txt", sep = "|", 
colClasses = rep("character", 22)))
    user  system elapsed
   0.852   0.021   0.872

I should probably have begun with this timing. Its not my 
intention to turn this into a speed-only competition, however the 
ingest of files and speed of calculation is very important to me.
