Hi, Sometimes (not always) when I do a 'portupgrade', it takes _ages_ to "update the ports index", without actually placing any noticeable load on the system. In ports/UPDATING, it says (of make index) "This may take an undesirably long time.". That would be fine, *if it were doing any work*. I try to speed it up by "renice"ing all the processes I can pin down as belonging to the portupgrade (is there a recursive renice for child processes?), but it makes no difference. Here's a grab of "top", after I've been staring at "Updating the ports index ... Generating INDEX.tmp - please wait.." for about 10 minutes.... PID USERNAME PRI NICE SIZE RES STATE TIME WCPU CPU COMMAND 65942 rich 101 0 37396K 27732K select 0:01 4.18% 2.39% kdeinit 62156 rich 96 0 52072K 40144K select 0:04 1.69% 1.56% kontact 557 root 96 0 102M 48316K select 15:39 0.88% 0.88% Xorg 67154 root 8 -5 7304K 7180K wait 0:00 2.96% 0.54% make 67520 root 8 -5 928K 800K wait 0:00 3.00% 0.15% make notice that a) there's almost no load on the system b) I managed to catch some of the make's and renice them c) It didn't help These two makes soon disappeared from the top of the list, leaving only background processes. It doesn't have any open network connections, so I'm not waiting for a remote machine; it doesn't have any system load so I'm not waiting for processing; the hard disk is (largely) idle, so I'm not waiting for i/o, but I am still waiting! How can I make it stop messing around and get on with it? Thanks, Rich
