The GNU sort you're using is an OSR5 binary, compiled against OSR5 libc.
It's not surprising that it performs similarly (perhaps a little
surprising that it's actually _slower_...)  There's a chance that the
GNU sort source tree includes alternate collation libraries that would
be faster, if you built it that way.  But since the UW binary is doing
what you need, that's probably what you should use...  Your tests
actually show it to be about 15% faster than the Xenix binary you were
previously using.

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
