Subject: works slower than Storable::dclone on hashes with big number of keys (Documentation update?)
Hi In the Debian Distribution the following Bugreport was reported: http://bugs.debian.org/516409 ---(snip)---- Package: libclone-perl Version: 0.31-1 Severity: normal The documentation says that Clone::clone works faster than Storable::dclone. However, this is not true for hashes with big number of keys. A simple attached benchmark shows the difference by two factor, and on my real-world examples this number increases to three. Please advance the documentation for Clone accordingly. ---(snap)---- the benchmark is also attached to the bugreport at the above URL. Many thanks for consideration! Bests Salvatore

Hi Salvatore, thanks for the report! We have updated the mention in 0.32 to note how dclone() is faster for deeper structures, while clone() is faster for shallower ones. The 0.32 update also fixes a long-standing issues with cloning Fieldhashes, so a downstream update is advised. Thanks! breno
