B::Size2::Terse is a fork of B::TerseSize 0.09.
The B::Size and B::TerseSize modules attempt to measure the size
of Perl op codes. The output of <B>B::TerseSizeB> is similar to that of
B::Terse, but includes the size of each OP in the tree and the
PADLIST (subroutine lexical variables). The module can be run just as
other compiler backends or used via Apache::Status (version 2.02
If the Apache::Status StatusTerseSize option is enabled, there
will be a main menu item added, Memory Usage. Clicking on this link
will cause B::TerseSize to produce a summary of package memory
usage. This summary can take quite a while to produce, as each
package subroutine syntax tree will be walked, adding up the
information. This information will be cached, so running httpd in
-X (non-forking mode) is a good choice.
When browsing the Apache::Status Symbol Table Dump, a Memory
Usage link will be at the bottom of each page. These summaries
also include measurements of package global variables.
The Apache::Status symbol table browser will also provide an option to
dump a subroutine tree along with the other subroutine options.
