Summary: Scantime is very long unless "use bytes" hack is used
Product: Spamassassin
Version: 3.2.3
Platform: Sun
OS/Version: Solaris
Status: NEW
Severity: normal
Priority: P5
Component: Libraries

# spamd -V
SpamAssassin Server version 3.2.3
running on Perl 5.8.8
with zlib support (Compress::Zlib 2.004)
# uname -a
SunOS ornl71 5.9 Generic_118558-39 sun4u sparc SUNW,UltraAX-i2
Problem has been present since SA v3.2.1
Some messages take a very long time to scan (on the order of several minutes).
This time is reduced substantially if "use bytes" is added to Message.pm. For
a test case, I did the following to minimize the effects of network lookups
and local rules:
Added -L and -D to spamd startup
Turned off Bayes, AWL, razor, pyzor, DCC.
Set dns_available to "no".
Removed SARE and locally-defined rules.
Scanned the test message with spamc.
Results
With "use bytes" hack: 4 seconds
Without the hack: 23 seconds
Adding in SARE and local rules makes the gap even wider:
With "use bytes" hack: 16 seconds
Without the hack: 122 seconds
