I agree with the principle of correctness, but let's be honest - it's (many) orders of magnitude between ByteString and String and Text, not just a few percentage points…
Well, your benchmarks are highly suspect. See below.
Data.ByteString.Lazy.UTF8 (system readFile + fromString + length) - 11 seconds, correct length.
You should be using bytestring I/O for this.
Data.Text.Lazy (system readFile + pack + length) - 26s, correct length.
You should be using text I/O for this.
