Single-thread performance of the T1-T3 CPUs is indeed very low
compared with x86-CPUs. The T4 CPU catches up, hopefully the T6 will
do the next big step!

Quoting Jersey Man :
Wondering if anyone has any insights
I have a simple bash script which spawns many (~1000) processes in a
while loop - each goes into background
On Debian/Sparc the time taken for each iteration gets delayed every loop
The same script on X64/RHEL simply flies... Are there any throttling
limits on Debian which may be slowing process creation. Getting a
1000 such process takes over an 1 1/2 on Debian/Sparc while on the
X64 server it takes about 1/3 the time. Both servers have identical
memory and the CPUs are Niagara T1 vs XEON 4 CPU
Or is the XEON so much faster?
