Or should I go on stracing?.. No neat ideas I'm afraid but if you decide to go through with it please post your experiences back to the list. A program, 'dtop' perhaps, would be nice. I know 'atop' (ftp://ftp.ATComputing.nl/pub/tools/linux) tries: <<Unfortunately, the standard kernel does not maintain counters about the number of disk and network accesses issued per process.>> but the author hasn't posted his kernel-patches yet(?) I guess 'strace -p'ing is one way, very frequent sampling of all processes like 'top d 0' is another. Either way some programming and/or scripts will probably be needed. -- //Björnen, ngn på nerdtalk har ngn idé?
