Pessoal , alguem tem comparações de performance
entre o FreeBSD e o Linux mais recentes ?

1º) These are the results with both running the
same source code of Apache 1.3.12, obtained
from the Apache.org website and recompiled
locally on each OS.

Under Linux, the repeated (10 runs each) and averaged results for the same
benchmark were:
Totals per operation:
Operation seconds
alter_table_add 287
alter_table_drop 186
connect 7
count 83
count_on_key 893
create+drop 4
create_index 3
insert 24
order_by 189
order_by_key 174
select_distinct 37
update_with_key 182
TOTALS 2069
And under FreeBSD:
Operation seconds
alter_table_add 225
alter_table_drop 181
connect 10
count 73
count_on_key 821
create+drop 8
create_index 7
insert 31
order_by 132
order_by_key 140
select_distinct 21
update_with_key 169
TOTALS 1818
The Sendmail benchmarking showed results slightly more
favorable to Linux. All tests were repeated 10 times,
as with the MySQL benchmarks, and they averaged:
Linux FreeBSD
Incoming e-mail: 317 mails/sec 289 mails/sec
Mail relaying: 182 mails/sec 214 mails/sec
Fetchmail POP3: 92 mails/sec 98 mails/sec
Fetchmail incoming: 17 mails/sec 15 mails/sec
-------------------------------------------------------------------
Several times, after going through hours of stress testing,
the Linux box would not let me log in with a simple rlogin or rsh.
In those cases, I had to go through a standard telnet session to
access the server. This odd behavior was not reproducible,
but did occur five times, always after several hours of
load testing. The FreeBSD OS never showed any odd behavior.
Occasionally, when the virtual memory was earnestly overloaded,
launching a simple "ps aux" would take four or five seconds on
the Linux 2.4.0 while waiting for some pages to be freed.
Tweaking the VM subsystems (see Tuning Linux For Max Performance)
did help a lot. No tweaking was necessary on FreeBSD. It follows
that FreeBSD does a better job at self-tuning its VM than Linux 2.4.0.
Conclusions
Linux 2.4.0 is available for no money. So is FreeBSD.
Linux uses advanced hardware, so does FreeBSD.
FreeBSD is more stable and faster than Linux, in my opinion.
We penguinistas sometimes believe we are having more fun
than anybody. But then I lean over the fence and discover
the FreeBSD folks are having a hell of a party, too.
And their OS is as fast as I have seen.
I have to ask myself why I don't just switch my server to FreeBSD.
