Sun-tar and GNU-tar both unpack in small blocks by default. Did you try star? Star by default sets up a two process system with a shared memory in between (called FIFO). This shared memory allows star to operate in larger block sizes. Note that you may need to call "star -no-fsync ..." to get the maximum unpack performance as star by default operated in a mode that allows to grant that all files really have been unpacked to stable storage. ftp://ftp.berlios.de/pub/star/ Jörg -- EMail:jo...@schily.isdn.cs.tu-berlin.de (home) Jörg Schilling D-13353 Berlin j...@cs.tu-berlin.de (uni) joerg.schill...@fokus.fraunhofer.de (work) Blog: http://schily.blogspot.com/ URL: http://cdrecord.berlios.de/private/ ftp://ftp.berlios.de/pub/schily _______________________________________________ zones-discuss mailing list email@example.com
