This matrix takes an O(N^2) of storage.
e.g. this file is already 35MiB in size:

Alternative could be to provide each instruction with simple cycle number instead of graphical matrix

unused macros can also be trimmed

@jnk0le Have you tried conf.visualize_reordering = False and/or visualize_expected_performance=False?

[jnk0le]

missed that

In fairness, it's not properly documented.

@jnk0le If you have a minute, feel free to open a PR for this.
