ive gone with schedtool and ionice for now (seems to be working) and |
| 8 |
will configure that as the defaults when this run finishes. I have not |
| 9 |
built the bfq scheduler in this kernel so will give that a try later - |
| 10 |
its currently using mq-deadline with a WD blue SSD (will bfq be better |
| 11 |
than a deadline on an ssd? - will try it and see). It has 4g ram and 4g |
| 12 |
swap with about half in use - in normal running swap isn't used much, if |
| 13 |
at all. |

As well as emerge, the io load is also coming from the network as I have |
| 16 |
3x1g bonded interfaces routing busy vlans including a moosefs SAN and a |
| 17 |
100mhz uplink which was suffering delays and timeouts. The root cause |
| 18 |
is trying to do too much with too little - :) |
