Hi,
I must be doing something silly. I have a 900MHz, 384MB RAM, and
this thing is slow. (Postgresql-7.1.2).
And growing exponencially slower.
SQL: http://John.Vicherek.com/slow/schema.sql (save to /tmp/schema.sql)
am.dat: http://John.Vicherek.com/slow/am.dat (save to /tmp/am.dat )
perl: http://John.Vicherek.com/slow/rpm2filerian.pl (save to /tmp/rpm2filerian.pl)
when I do :
createdb filerian
psql -d filerian -f /tmp/schema.sql
echo 'create table times (the_moment datetime, the_number int4);' | psql -d filerian
cd /tmp/mdk/8.2/i586/Mandrake/RPMS # lots of RPMs here
while sleep 10 ; do echo 'insert into times values( now(), count(file.id));' | psql -d filerian ; done 2>&1 >/dev/null
&
for i in *.rpm ; do echo $i ; perl /tmp/rpm2filerian.pl 0 $i ; done
Why are the times so bad ? Why is it slowing so fast ?
Am I missing any useful indeces ?
This shows the slowage:
select the_number,min(the_moment) from times group by the_number;
PS: if you look in the perl code for "exec", immediatelly above will you
find the query it is doing.
Thanx,
John
