Changing the swap partition's size is not strictly necessary, because Irix supports both swap partitions and swap files.
See https://techpubs.jurassic.nl/manuals/065.../ch06.html
for more information on how to add swap files if they become necessary to run your programs. That being said, you can enlarge the swap partition if it seems too small. If there is more space on disk than you are going to need, a swap partition between 1X-2X the size of RAM is a reasonable starting point. You should not make the swap partition smaller than the default (so 128MB under 6.5) as there could be problems.
