The control.cancel group had 384000 entries in it's directory. The directory itself was > 8 MB and an rm -rf to remove it has been running now for more than 90 minutes. I renamed the directory and the througput instantly went up to 300 articles a minute. Some other people have suggested I lower the interleave factor on the ccd array. I took the advice of the ccd man page and set the interleave factor to 65536, however someone else has suggested using 1024. Any thoughts either way ? Thanks for your help anyway. regards damian -- * Damian Hamill M.D. damian@cablenet.net * CableNet & The Landscape Channel * http://www.cablenet.net/ http://www.landscapetv.com/
