Hello,
some reasons :
* the ports tree built out of a very large number of little files
* the creation of files involves modification of "meta-data" (that is data describing the organization of files on the disk)
* the meta-data modifications are generally done synchronously (the operation succeeds only if the data are really written on disk)
* the 2.2.x branch does not use DMA on IDE drives
TfH

Subject: why is cp so slow?
Hi All,
why is moving /usr/ports to another Partition taking over 1/2 hour?
That's only 4MB. I am using freebsd-stable-2.2.7.
