Is this only my N900 @PR1.1 or others also experience overall device sluggishness after ~2-3 days of uptime? There is semi-identified problem with hildon-home hogging CPU time for few seconds on each wakeup from standby [1], however that's "fixable" by <i>killall hildon-home</i> and re-adding widgets to desktop. Most likely case is memory leak in one of the widgets on desktop, however that hasn't been determined yet.<br>
<br>Apart from hildon-home, I've noticed my N900 is still misbehaving after few days since last reboot. Namely, it becomes very unresponsive at times, to the point where -- for example -- I can hear incoming call ringtone, but screen doesn't really catch-up, so I don't even have opportunity to see who is calling, not to mention taking that call. This is obviously quite annoying, however I am very far away from taking "reboot your device every second day" advice as a solution.<br>
<br>What I am suspecting here is swap (over)usage. It does only seem to grow over time, rather than going down when I close unused apps, for example. Physical RAM, on the other hand, usually sticks around 180-200MB of use, regardless of apps opened in the background. I've seen browserd takes quite a lot of memory resources, so I usually do <i>/etc/init.d/tablet-browser-daemon.init restart</i>, which seems to release some memory, but not for very long tough.<br>
<br>Other thing I've noticed is system swappiness value, which is 100 by default. What I've learned [2] is that 100 value favours moving stuff to swap space quite frequently, which makes some sort of sense with experience I've got. I have rebooted my N900 today and set swappiness value to 60 by <i>echo 60 > /proc/sys/vm/swappiness</i>, however I am not sure whether that's right way of setting this (article refers to /etc/sysctl.conf file which simply doesn't exists in my rootfs, or perhaps is stored elsewhere). Anyway, I am going to observe how system overall performance evolves over next couple of days.<br>
<br>Does anyone experience similar sort of problem in his/hers N900 and has some thoughts on the topic? Any input would be appreciated. Apart from "reboot" solution, of course.<br><br><br>[1] <a href="https://bugs.maemo.org/show_bug.cgi?id=8723">https://bugs.maemo.org/show_bug.cgi?id=8723</a><br>
