Car: Dolphin 26.08 and KIO performance improvements

Meven Car has written a pair of interesting blog posts (part1,part2). Thefirst post is largely about some of the recent new features and performance workthat have gone into the Dolphin filemanager 26.08 release, as well as the KIO framework. The second looks atthe performance improvements and benchmarks for previous, current, and upcomingreleases.

Copying many small files is more than twice as fast as it was in April. Thegain falls off as files get larger, which is what you would expect: the fix isto the per-file overhead, and once each file carries a megabyte of actual I/Othe overhead stops being what you are waiting for.

There is still a gap with cp, discussed at length in theJuly post. KIO is doing more than cp does, but not five times more,and the batching work that closes most of the rest of that gap is still inprogress.
