For large tar.{gz,bz2} files, getting at the last file in the archive is slow. An advantage of zip files is the optional presence of a table of contents which allows faster access of single files.

It's probably due to unpredictable write buffering and/or low timer resolution. Try timing with multiple passes of the same file on a ramdrive.
