It may be worth testing an M3000 unit that has a Fujitsu SPARC-VII+ processor in it. I have one : $ psrinfo -pv The physical processor has 8 virtual processors (0-7) SPARC64-VII+ (portid 1024 impl 0x7 ver 0xa1 clock 2860 MHz) System PROM revisions: ---------------------- OBP 4.33.5.d 2012/07/18 06:55 $ prtconf -v | grep "Memory" Memory size: 65536 Megabytes So if the cpu is the issue then it may be interesting to look at.
