This is not an obviously correct assumption. A 100MB footprint with non-trivial extra I/O out of the blue (not in response to an explicit user action) is more than enough to interfere with other things you're doing regardless of focus, particularly the performance-critical things given as examples above. </pre> </blockquote> <pre wrap=""> This should be an important concern. It should be simple to write a very small C program that would start up, look at the system load running applications and available RAM and then only start a secondary application (such as an automatic update) when some conditions are met, for example system load <0.5 over last 15 minutes, 200Mb of free RAM (including cache RAM at 2:1 ratio). Then automatic security updates could be done in the background (if user so chooses) and also a button could be added to the update-manager to "Upgrade when idle". </pre> </blockquote> <br> Yes, this is an approach we can pursue. Michael Vogt and MPT are looking at low-hanging fruit in this regard for 9.04, and we can make a bigger push to improve it in 9.10.<br> <br> Mark<br> </body> </html>
