		<description>I thought it was weird when you mentioned how long Python took to startup after a few days of uptime because I&#039;d never seen that. I compared compiles on my Dual 1.8 G5, 2GB RAM. 

mark@eagle:/usr/local/src/subversion-1.3.0$ uptime
22:15  up 13 days,  9:40, 2 users, load averages: 0.39 2.67 2.21

Downloaded subversion, opened Terminal and did the tar-configure-make dance:

mark@eagle:/usr/local/src/subversion-1.3.0$ time make -j8
.
.
real    3m29.461s
user    3m45.418s
sys     2m31.063s

That&#039;s with all my apps open, and my wife logged in via fast user switching. gcc 4.0.1.

I immediately ran the make a second time and shaved 4 seconds off.

The 4 second difference doesn&#039;t seem like much, but is a bit curious. On a Linux box I did the same test and got:

real    1m16.499s
user    1m53.587s
sys     0m34.572s

That was the second run. First run was about 0.6s slower. Not nearly as much of a difference between runs. The Linux box has been up for 122 days and is running several instances of Tomcat and Zope, so it&#039;s anything but &quot;fresh&quot;.

Coming to Mac from the UNIX world, I have to admit that I normally leave my G5 running all the time, only rebooting to apply security updates.</description>

		<description>The version of gcc also seems to matter. The above numbers are for gcc 3.3 on the G5 and gcc 4 on the iMac. When I changed to gcc 4 on the G5 and rebooted it took 3:05.</description>

		<description>No. I didn&#039;t bother because I hadn&#039;t been using it very hard. (The G5 is still my main Mac.) But, for consistency, I just ran the compile after rebooting the iMac, and it took 1:56.</description>

		<description>Interesting.  I didn&#039;t quite believe that daily reboots would help, but this is pretty good evidence.  I&#039;ll ask that people give #s in the future by 1. quitting all apps, and 2. another set after rebooting.

Incidentally, did you reboot your iMac Core Duo before running the compile that gave you 1:57?</description>
