My typical setup is made of 4 workspaces (1 dedicated to a cpu-intensive CLI application, 1 to Thunderbird, 1 to Chrome and/or Virtualbox, and the last one to 6-8 Nemo windows and 2-3 CLI terminals) - plenty of RAM, so no special issue here - and the laptop remains on round the clock.
I've found a number of improvements w/ respect to the former version contained in 17.1 (speed, snappy windows effects, general response time), however I've noticed some remaining issues along the subject of this post.
For the first day of usage, everything appears normal - Nemo uses some 100 MB of RAM, new windows open snappily. However, after the first day or so, Nemo becomes increasingly unresponsive:
- new windows open with increasing lags, from seconds to minutes. After 2 days of usage, I'm finding somehow common to have to wait 10+ minutes (!) for a new window to appear (both for windows opened as children of former windows and for windows opened from the panel);
- Nemo's memory usage increases, up to 1.5 GB (!), absorbing almost fully one of laptop's 4 cores (cpu in the 70/80% range);
- windows become sluggish and their content is not refreshed any more (neither spontaneously, nor via F5);
- Nemo becomes also unresponsive to ctrl-alt-esc - nothing happens;
- other running applications in the meanwhile do not show any significant slowdown.
I'm attaching the output of a pmap -x, in case this may help in shedding some light on what's going on.
Any help is greatly appreciated
