Swap partition
Enabling the journalling diminshes the write speed by about 10%. (the read speed is unaffected). This loss is trivial except for write intensive tasks. On such task it Swap (paging). And there is no reason to journal swap that I can think of.
Swap partition
Maybe so, maybe not. Once the swap mechanism allocates a chunk o' disk (I think in 80MB chunks -- can't rememebr, maybe 800? Doesn't matter. Big chunks, anyway), it uses some extremely low level API to read/write pages of memory to the swapfiles. |
