俺8个G的内存怎么只剩几K了,巨怪异!
man topas:
PageIn
Number of 4K pages read per second over the monitoring interval. This includes
paging activity associated with reading from file systems. Subtract PgspIn
from this value to get the number of 4K pages read from file systems per
second over the monitoring interval.
PageOut
Number of 4K pages written per second over the monitoring interval. This
includes paging activity associated with writing to file systems. Subtract
PgspOut from this value to get the number of 4K pages written to file systems
per second over the monitoring interval.
MEMORY Displays the real memory size and the distribution of memory in use.
Real,MB
The size of real memory in megabytes.
% Comp
The percentage of real memory currently allocated to computational page
frames. Computational page frames are generally those that are backed by
paging space.
% Noncomp
The percentage of real memory currently allocated to non-computational frames.
Non-computational page frames are generally those that are backed by file
space, either data files, executable files, or shared library files.
% Client
The percentage of real memory currently allocated to cache remotely mounted
files. |
