这个正常的,因为最后是累加,不要考虑这个主要看pss,
它的pss是把共享部分平摊到每个进程中.而总计比较接近oracle使用大小的.
当然不包括共享内存段.
# smem -c a
unknown field a
known fields:
command process command line
maps total number of mappings
name name of process
pid process ID
pss proportional set size (including sharing)
rss resident set size (ignoring sharing)
swap amount of swap space consumed (ignoring sharing)
user owner of process
uss unique set size
vss virtual set size (total virtual memory mapped) |
