The wasted memory is also present on the VAX and not only on the RT.
John Elsj (vs2RC, 3Meg wasted), will send in another report tomorrow. On
FLAKEY, a 6meg machine the following was noticed at the end of the day:
flakey% pstat -s
9797k used (2368k text), 6411k free, 2357k wasted, 256k missing
avail: 9*512k 2*256k 2*128k 5*64k 9*32k 14*16k 203*1k
Notice the large wasted, and the relatively few number of large segments
used.
Richard thinks it may be Don's old fix (vm_drum.c and vm_text.c).
JFC is compiling a RT kernel without Don's changes and will let us know the
results.
