| Subject: | Very slow parsing |
Email::Simple seems very slow at building the headers from a normal,
25-line e-mail header: it clocks at about 5 messages parsed per second.
I tested this on a 3.2GHz Pentium running RHEL, and on a 1.8GHz Pentium
M running Windows XP. Benchmark attached.
Hope that helps,
