Ouch indeed. That's pretty bad. It's believable when I think back to the purpose of these chips: handling workloads that were more I/O and concurrency bound than CPU bound. So, probably identify and eliminate these problems early on even if developer has to drop some threads or cores.
Note: There's always my other recommendation of turning open-source Leon3 into a multicore. Im curious what it or Leon4 get on such a benchmark versus Intels on similar process nodes.
"SPARC chips before T4 under-perform on GMP. This is not because the GMP code is inadequately optimised for SPARC, but due to the basic v9 ISA as well as the micro-architecture of these chips. The T1 and T2 chips perform worse than any other SPARC chips; they compare to a 15 year older 486 chip."
ouch!
