is there a noticeable speed performance difference when you cache the data which you retrieve
from the database to a file on the filesystem (eg.: htdocs/cache/cachefile) rather than grabbing it directy from the MySQL DB?
Thanks a lot!
This highly depends on your disk IO, the size of your database, the database configuration, the link to your database, the optimization of the database, etc, etc. So there is no definitive answer to that.
You might want to consider memcached for your caching problem you have. Since you provided no information about the actual issue i’m in doubt you’ll get good answers to resolve your problem. Or do you just want to know if disk-io is faster than mysql? 😉
