The assumption is that the optimizer uses a lot of memory. But you'd need
to replace the packages' default optimization level to see an effect.

First and best thing you could do is probably looking for a 64 MB SIMM (I
don't know if 72 pin SIMMs ever came in 128 MB a piece). Borrowing from an
old Volkswagen saying, memory is irreplaceable, except by more memory.

Second, you could grow your swap partition, or add a second disk with
another swap partition. But swap is slow, and at twice the RAM size, you
are looking at diminishing returns.

Let us know how it's going.
