#2 [Windows] RAM disk Performance (性能)

By the way, I have set TIMEFMT environment as follows:

m08@makoto 23:30:17/140225(/usr/pkgsrc)% echo $TIMEFMT
%U %S %*E %P %X+%Dk %I+%Oio %Fpf+%Ww

On My diary on 2014/01/30, I had first experience on RAM disk on Windows (Softperfect version).
Before RAM Disk (without RAM disk, by the way, please IGNORE the error indicated):

cd /usr/pkgsrc/security/openssl; time bmake package
...

cp: cannot stat `libcrypto': No such file or directory
Makefile:548: recipe for target 'install_sw' failed
gmake: *** [install_sw] Error 1
*** Error code 2
Stop.
bmake: stopped in /usr/pkgsrc/security/openssl
*** Error code 1
Stop.
bmake: stopped in /usr/pkgsrc/security/openssl
397.29s 323.12s 13:36.14 88% 0+0k 0+0io 36000495pf+0w
m08@makoto 23:26:53/140225(..security/openssl)%

With following line in /usr/pkg/etc/mk.conf, all build related read/write will be done on RAM disk (I hope).

m08@makoto 23:36:54/140225(/usr/pkgsrc)% grep WRKOBJDIR /usr/pkg/etc/mk.conf 
WRKOBJDIR=/cygdrive/g/WRKOBJDIR

(After RAM disk setup):

cp: cannot stat `libcrypto': No such file or directory
Makefile:548: recipe for target 'install_sw' failed
gmake: *** [install_sw] Error 1
*** Error code 2

Stop.
bmake: stopped in /usr/pkgsrc/security/openssl
*** Error code 1

m08@makoto 23:43:35/140225(..security/openssl)%

Too many page fault implies that amount of disk i/o ?
Page Fault が多いということは、disk i/o があるということかな。

Configure doesn't recognize this system and doesn't know
what module to assign to it.  Help the cause and run the
following command to let the maintainers know about this
deficiency!  Thanks.  Just cut and paste the following:
uname -a | mail -s cygwin bill@lefebvre.org

何だか、このプログラム、全然信用出来ない気がする。
それとも僕が何か(趣旨を)間違えているかな、
