This fix for php (posted by ricardohenrylee@gmail.com) should be
applied to the code for "top"; it (and /usr/bin/time -v) think the
page size is actually 64k, and reports RESident size as 16 times what
it should be.
# if HAVE_UNISTD_H
# include <unistd.h>
# if defined(_SC_PAGESIZE)
+# ifdef __CYGWIN__
+# define REAL_PAGE_SIZE 4096
+# else
# define REAL_PAGE_SIZE sysconf(_SC_PAGESIZE);
+# endif
# elif defined(_SC_PAGE_SIZE)
# define REAL_PAGE_SIZE sysconf(_SC_PAGE_SIZE);
# endif
Cheers,
Marty

How is top measuring the memory of process ?
/proc/<pid>/statm
should report the correct info in
sysconf(_SC_PAGESIZE) = 64K units.
