My benchmarking indicates that reusing the buffer makes string-pixel-width only 10 times slower than string-width, i.e. 50 about microseconds per call.
Can you please paste the exact code you used? As I wrote in my previous mail, I tried without buffer switching, but it was still 50 times slower. 10 times slower is still not good, but given that number I may stop arguing, since the factor will be even less in real code.
