PHP memory limit

While trying to import the GenoOntology terms, I got the following error message:

PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 31 bytes)
I believe we need at least 2 GB of memory to do most tasks in a sensible way. If we hit that limit again, it maybe has to be increased further. On my laptop, it is 6 GB and with that I could import everything.
Support has changed the limit:

Done: memory_limit = 2048M.
This setting has to be made in php.ini
