Hi Stewart, Thank you for filing this report. I will wait for your patch, since you are OCA. Meanwhile, I will have to do some analysis of my own ..... Hope to hear from you soon ......

Hi Stewart, First of all, let me inform you that we do not support PPC architecture. However, this does not preclude performance improvements. What you are proposing is already implemented, so this leads to this bug being closed. Note that in 8.0, the function skip_trailing_space() has been rewritten, no more uint8korr, just memcpy() eight bytes at a time, which should be considerably faster. Not a bug.

#98520 has some hope for the remaining korr implementations. Even look good on power.
