That only means you're increasing the constant factor in the complexity of the thing... which may very well be completely negligible unless someone provides real benchmarks. I would be very surprised if that "2 times" factor happens to be true, because finding a string in a file is an order of magnitude simpler than sourcing said file with bash. Moreover this doesn't take into account disk and os cache. Alexis.
