lubuntu - How does the size of the persistent file in a live version affect performance?


Having, say, a 4GB USB pendrive, if 0.5GB is reserved for the persistent installation, will this perform better or worst than reserving 1, 2 or 3GB? Let's assume that little space is needed, way less than 0.5GB. When the live version boots, does it take longer in reading this partition (affecting the setup time)?, or will it be limited to swap memory (affecting the run time)?


In particular, I'm dealing with a Lubuntu 16.04 live version for computers with limited resources (~1GB RAM), and have installed GNU Octave, occupying some 300MB of the persistent memory.



Persistence is the space on your USB stick used to store information, so that the information is still there after a reboot. The size won't affect performance. Having more space will allow you to have more information, including files, available between boots.
