Can swap-in be improved?Can swap-in be improved?Posted May 24, 2007 14:44 UTC (Thu) by mgb (guest, #3226)In reply to: Can swap-in be improved? by MathFox Parent article: On-demand readahead
DIMMs are cheap in this part of the world but laptops to holder larger DIMMs are not. In some circumstances it is economical to have sufficient RAM to hold one or two apps but to use swap when three or four are open and temporarily idle.
The thought was that one could overcome the slow random swap-in reads by reading ahead pages from swap which had been used earlier and would probably therefore be used again.
