“Last week I got a call from Stalker Software Inc. Stalker makes
CommuniGate Pro, a full-featured mail server that supports SMTP,
POP3, IMAP4, ACAP, LDAP, and a few other standards acronyms. It
includes an extremely well-designed Web-based administration system
and Web-based access to email. It includes antispam features,
mailing list management, and even personal Web sites for your
users.”
“The reason Stalker called is because, according to the
company’s own benchmarks, CommuniGate Pro on Linux skunks Microsoft
Exchange in terms of performance, based on Exchange benchmarks
performed by IBM. The comparison is between Exchange 5.5 SP2
running on Windows NT 4.0 SP4 versus CommuniGate Pro 3.1 running on
Red Hat Linux 6.0…”
“LinuxWorld does not endorse either benchmark, but we find
them both to be believable. And that isn’t only because — unlike
the recent benchmarks by Mindcraft and ZD Labs — these results
tend to support the anecdotal evidence that Linux outperforms
Windows NT.“
