Since the GP mentioned it is a machine from 1998 I would expect it to be PII with a clock above 200MHz. Since the Moore's law actually worked in the 90's that machine will be a lot more powerfull than that 586 (from 94-95 I guess). On top of that curves and chacha20 could be used for ssh to reduce the CPU load.
