PhpSpreadsheet holds an "in memory" representation of a spreadsheet, so
it is susceptible to PHP's memory limitations. The memory made available

to PHP can be increased by editing the value of the `memory_limit`
directive in your php.ini file, or by using
`ini_set('memory_limit', '128M')` within your code.

Some Readers and Writers are faster than others, and they also use
differing amounts of memory. You can find some indication of the
relative performance and memory usage for the different Readers and
Writers, over the different versions of PhpSpreadsheet, on the
[discussion
board](http://phpexcel.codeplex.com/Thread/View.aspx?ThreadId=234150).
If you've already increased memory to a maximum, or can't change your
memory limit, then [this
discussion](http://phpexcel.codeplex.com/Thread/View.aspx?ThreadId=242712)
on the board describes some of the methods that can be applied to reduce
the memory usage of your scripts using PhpSpreadsheet.

Not all features of PhpSpreadsheet are implemented in all of the Reader
/ Writer classes. This is mostly due to underlying libraries not
supporting a specific feature or not having implemented a specific
feature.
