I noticed recently that the sort utility is slower than than on Ubuntu 10.04 (at least for what I'm doing). While sorting an 8Gb text file with params such as sort -S 14G -k 3,3 -k 4,4n, I noticed that the older version (7.8 I believe is the version on Ubuntu) performed the sort in about 10 minutes, while it takes roughly 3 times as long for the most recent version in Fedora. Nothing is being written to disk in either case, just to be clear (I used the home dir as the temp dir so I could check easily enough). Is there a reason for this? Seems like too noticeable a performance regression for it to have simply been ignored. I'm still playing with things, but I wondered if anyone else had faced the same issue? I might just go ahead and recompile the older version and use it for the time being. I have to do this task often enough that it seems as though it might be necessary...
