Building a certain GCC configuration on a freshly booted system: 11 h. Remove build tree, build it again (2nd): 12 h 50 min. Huh. Remove build tree, reboot, build it again (1st): back to 11 h. Remove build tree, build it again (2nd): 12 h 40 min. Remove build tree, build it again (3rd): 15 h.

< antrik> tschwinge: yes, the system definitely gets slower with
  time. after running for a couple of weeks, it needs at least twice as
  long to open a new shell for example
< antrik> I don't know whether this is only related to swap usage, or there
  are some serious fragmentation issues
< braunr> antrik: both could be induced by fragmentation

<manuel> interestingly, running it several times has made the performance
  drop quite much (i'm getting 400-500MB/s with 1M now, compared to nearly
  800 fifteen minutes ago)
<braunr> manuel: i observed the same behaviour
