巨大的阵列

Question

I'm planning to store gigantic arrays into serialized files and read from them in order to display data within them. The idea is to have a simple, document-oriented, filesystem database. Can anyone tell me if this would be a performance issue? Is it going to be slow or very fast?

Is it worth, filesystem is always really faster?

Answer 1

It will be very slow. Serializing and unserializing always requires reading and processing the whole array, even if you need only a small part.

Thus you are better of with using a database (like MySQL). Or if you need to only access key/value use APC/memcached.
