Sorry about these questions. I am used to working with DBs with less
then 10K rows and now I am working with tables with over 500K rows
which seems to be changing a lot for me. I was hoping I can get some
I have a 'companies' table with over 500K rows and a
'purchased_services' table with over 650K rows.
The following query takes over 6 seconds:
SELECT * FROM purchased_services WHERE (purchased_services.company_id = 535263)
purchased_services.company_id has an index on it.
The following query takes over 3 seconds:
SELECT count(id) FROM companies;
To me the time it takes to run these queries makes no sense. I would
imagine both of these queries would take a fraction of a second.
When running some of these queries and looking at 'SHOW processlist' I
was getting a lot of 'Writing to tmp'.
My DB engine is InnoDB. I am running this on my laptop that is a
PowerBook 867 with 756 MB of Ram.
Feedback and insight would be greatly appreciated.
Thanks my friends! :-)
