>direct string concatenation is 2X faster than using "implode"
That depends on how many strings you are concatenating. The beauty of implode is that you can build an HTML snippet and implode it all at the end before output.
Never checked that myself, but I believe you will get better results (performance-wise) with output buffering than with concatenating output for one big final `echo'.
