[08:41] <alkisg> So, this is my new test that shows the 4.4+ kernel issue where writes start fast, but end up 100 times slower: http://paste.ubuntu.com/24879399/
[08:41] <alkisg> I.e. copying /lib around, starts with < 10 sec, and now it's at 383 secs and rising
[08:42] <alkisg> At any point, if I run: "echo 3 > /proc/sys/vm/drop_caches", the problem goes away for a few minutes
[08:44] <alkisg> This is a 32bit installation with 16GB RAM. I suspect that some commit related to pagecache broke it at the 4.4 kernel
[08:44] <alkisg> So, my question is: can I play with something in /proc/sys/vm, that would limit all caching to under 4 GB, so that it won't have paging issues with the 32bit system, to see if that solves the slowdown problem?
