they bought that off cray, but in 01995 a few months after they released java, they (a different division) released the dual-processor ultra 2 https://en.wikipedia.org/wiki/Sun_Ultra_series
i had a dual-processor smp pentium pro under my desk by 01998, running windows nt 4.0 and occasionally java
really tho the bigger issue with java performance was that there was no supported native-code compiler until hotspot; though gcj was available, sun didn't support it, and i don't recall its performance as being that great. so by writing your code in java you were usually wasting 95% of your cpu on the bytecode interpreter, like python today. it wasn't something you'd do for things that required a lot of cpu

but that wasn't sun's first smp machine; the sparcserver 630mp, among others, supported four cpus in 01991 https://en.wikipedia.org/wiki/SPARCstation#Server_systems
