Is there a way to delay the start of the task queue during startup? My laptop has a few big fat bloated applications that start when the machine boots, then go dormant. They have to be there, I can't change them!

What I would really like to have this the ability to ask BOINC to wait 3 minutes before firing up background tasks. I did a quick test.

I am running BOINC with Rosetta / SETI projects attached. Booting with BOINC starting and Rosetta as the task, it takes about 4 minutes before the disk settles down and memory usage settles. Without BOINC, it takes about 2 minutes. The machine is swapping like crazy (4 GB of RAM). If I start BOINC manually after the machine settles, the combined time is about 2 minutes 15 seconds before all cores are running at full speed.

Mostly this is an issue with not being able to use my machine for the extra 2 minutes.

Thanks

See Client configuration in the BOINC wiki, especially the option:

<start_delay>nseconds</start_delay>
Specify a number of seconds to delay running applications after client startup. New in 6.1.6

Yes. Use <start_delay> in a cc_config.xml file.

<cc_config>
<options>
<start_delay>30</start_delay>
</options>
</cc_config>

The above will stop BOINC from doing anything after start up for 30 seconds.
Save the file as cc_config.xml in your BOINC Data directory. Default places for this directory are in this FAQ, or you can see this post of mine which shows where abouts it shows in your BOINC startup messages.

After saving, as an all files, in ANSI format, make sure BOINC knows about it.
BOINC Manager->Advanced view->Advanced->Read config file.
