Bug Description
Since at least 12.10, symptoms are that as time goes by I/O gets slower and slower (primarily if not even only writes rather than reads). It can be temporarily cured via /sbin/sysctl -w vm.drop_caches=2 and/or /sbin/sysctl -w vm.drop_caches=3 but the problem will re-appear again sooner rather than later. The problem seems also somewhat proportional on how much RAM is allocated. It does not seem to appear with less than 8GB (i.e., i saw it first when switching to a 16GB laptop/ThinkPad w530) and is considerably worse when allowing all memory compared to, e.g., by using only ~14GB using the mem=14000M boot option.
