Perl version supplied with RHEL has bug, which will result code running at least 100 times slower than expected speed. Now, Red Hat updated perl packages that fix a performance issue. Earlier only solution was installing your own perl under /usr/local or other location. This fix will now take care of performance penalty.
Perl is a high-level programming language commonly used for system administration utilities and Web programming.
These updated packages fix a large performance degradation. This issue was most noticeable when using “bless” and “overload” combinations, as well as when using the Perl DBI modules.
Users of perl are advised to upgrade to these updated packages, which resolve this issue.
How do I update perl under RHEL / CentOS Linux?
Type the following command
# yum update
