But, apparently, it's 2.2.x that doesn't handle large directories very well - 2.1.7 seems to work like a champ. It was taking 3-5 seconds to remove a file in a 300-400 entry directory with 2.2.1. It took only 3 seconds to remove all 300+ files with 2.1.7. [I booted up 2.1.7 with a fixit floppy, mounted the news partition and just did a "rm *" in control - *poof, they are all gone...] This is most definately a 2.2.x phenomenon... - Dave Rivers -
