| 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 | 08:41 |
| alkisg | At any point, if I run: "echo 3 > /proc/sys/vm/drop_caches", the problem goes away for a few minutes | 08:42 |
| 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? | 08:44 |
