I have an N800 w/ custom built kernel and everything is loaded from a 8GB SDHC card. It appear that the system is a little slugish on response after coming out of sleeping(kinda like me). Also, after boot up, my top read.
less than 8MB free, and 70+MB on cache? Is this normal, or you guys have any recommendation on what should we do to optimize the unit. Things to turn off, or *.conf to edit.Code:Mem: 118272K used, 8076K free, 0K shrd, 2096K buff, 76564K cached Load average: 0.10, 0.05, 0.03 (State: S=sleeping R=running, W=waiting)
Thanks.
But, as usual, smarter people might chime in now and expose my ignorance.

Karel Jansens is right. It is a feature of Linux (and many operating systems) that any file read from the file system is kept in memory for as long as possible, in case it needs to be accessed again. This is because file system access is (generally) much slower than RAM access.
"Cached" memory is basically free memory, though, since it has very low priority and will be trumped if applications need that memory for other purposes.
The load applet is aware of this and treats Cached memory as free memory.
