I've found that it isn't necessary to limit the tmpfs to half your RAM. I |
| 17 |
had it set to 6 GB on this box with 4 GB RAM. The kernel seems effective at |
| 18 |
managing this arrangement, swapping out to disk when needed - which, as you |
| 19 |
say, isn't often. When it does that I only find out by running top; it has no |
| 20 |
discernible effect on the desktop. |
