Speed Anomaly

As noted in a recent message I posted to freebsd-current, I saw a notable speed anomaly in building the 22 March -CURRENT (while running -CURRENT from 21 March). Briefly, my build machine took longer to complete the job than my laptop did.

I will provide the comparative raw timing information, then rather as ``appendices,'' information about the basic environment, the daily processes that I'm comparing, and the kernel configuration files for each of the build machine and the laptop. The following links to the build machine and the laptop will get you to copies of the /var/run/dmesg.boot from the boot when these timings were done.

For the build machine, here are the timings for the -CURRENT build:

Fri Mar 22 08:37:01 PST 2002
Script done on Fri Mar 22 08:37:03 2002

Ignoring the time taken for the cvs update, the build machine started at 05:32:58 and finished the make installworld at 08:37:21 -- a total time of 03:04:23.

In comparison, the laptop started the same process at 06:47:21 and ended at 08:36:13 -- a total time of 01:48:52.

Basic Environment

Connectivity here at the house is accomplished via a Pac*Bell residential ADSL connection, with a (single) grandfathered static IP address. The machine that is connected to the ADSL ``MODEM'' is a nondescript PC running FreeBSD -STABLE; it handles firewall and NAT duties.

On the ``inside,'' I have a couple of networks: the wired one, where the build machine is, and a wireless network, primarily intended for laptops and other mobile networking equipment. My laptop migrates between the two networks as circumstances warrant.

Each of the build machine and my laptop maintains a mirror of the FreeBSD CVS repository. Each also is able to boot from any of several slices; each slice has its own /usr/src, which I use as a CVS ``working directory.'' Each machine has a (single) /usr/ports directory, which is also treated as a CVS ``working directory.''

Daily Process

Each day, I set the machines up to perform the following tasks (while each machine is running the most recent -STABLE that I have been able to build and boot -- usually, the -STABLE from the previous day):

At 0347 hrs., the build machine (``freebeast'') fires off a cron task to use CVSup to get its CVS mirror re-synchronized with one of the ``official'' FreeBSD CVS mirrors. The latter part of this script performs a cvs update against /usr/ports. The script takes steps to prevent the build machine's cvsupd from accepting requests until it has finished synchronizing to its mirror.

At 0355 hrs., the laptop fires off a cron task like the above, but using the build machine as the mirror to which it synchronizes. (There are a few other respects in which the processes differ, but I don't believe that they are material to this discussion.)

As soon as the build machine has updated its CVS repository, I start a cvs update against the /usr/src for the (-STABLE) slice that is running.

As soon as the laptop has updated its CVS repository, I start a cvs update against the /usr/src for the (-STABLE) slice that is running.

In each case, I review the output of this (done under script and resolve any conflicts that may show up, and otherwise ensure that my sources are as similar to the ``officially sanctioned'' ones as possible, save for patches for which I perceive a need or that I am testing.

Once any conflicts are resolved, I exit script, then append to the same file as root, via sudo script -a. Within this script session, I issue a csh alias which is slightly different from one machine to the other:

On the build machine, it is:
whoami && mount && cd /usr/src && uname -a && date && \ make -j8 buildworld && date && \ make -DNO_WERROR kernel KERNCONF=FREEBEAST && date && \ make installworld && date && \ mergemaster -u 0022 -i && date && df -k

On the laptop, it is:
whoami && mount && cd /usr/src && uname -a && date && \ make -j4 buildworld && date && \ make -DNO_WERROR kernel KERNCONF=LAPTOP_30W && date && \ make installworld && date && \ mergemaster -u 0022 -i && date && df -k
For each machine, then:
- I then use sudo script -a to track the activities that correspond to issuing the above commands, but this time, under -CURRENT.
