mongo.pl PHASE_* options question

mongo.pl PHASE_* options question

[David Dabbs]

I’d like to reproduce the mongo tests as shown at 

	http://www.namesys.com/benchmarks/v4marks.html

The page presents the mongo options used to generate the results, but not
all of these are documented at 

	http://www.namesys.com/benchmarks/mongo_readme.html

,and they are not mentioned in the mongo distribution README.


FSTYPE= ext3 | reiserfs | reiser4
MKFS= mkfs.<FSTYPE>

DEV=/dev/hda2   (or whatever disk device) 
DIR=/mnt/testfs (mountpoint you must create)
FILE_SIZE=4000 
BYTES=512000000 
#
# To have results free from buffer cache influence, 
# settings must satisfy 
#
#    BYTES * REP_COUNTER > ramsize
#

MOUNT_OPTIONS=<fs-specific mount options passed to MKFS command>

NPROC=1
REP_COUNTER=1 
SYNC=off 
WRITE_BUFFER=131072 
GAMMA=0.2 

DD_MBCOUNT=768

#
# these are not documented
#
PHASE_COPY=cp 
PHASE_OVERWRITE=off 
PHASE_APPEND=off 
PHASE_READ=find 
PHASE_DELETE=rm 
PHASE_MODIFY=off


A quick scan of mongo.pl code that validates options shows that the PHASE_*
options are not present, so it is safe to assume that the PHASE* options are
defunct. If this is the case, perhaps these options should be removed from
the page.

Hello,

unfortunately this is the very old mongo version. Please try the new one :

http://www.namesys.com/benchmarks/mongo-2003.06.24.tar.gz

which has an ability to selectively turn phases on/off.

The new options documentation will be added tomorrow.

Thanks,
Lena.

Glad I could help! BTW, could someone please send notice to the
reiserfs-list when the mongo package is updated? Thanks much,
