The issue should therfore more on the way T1 proc is working. I know that I/o is very slow (EMC navisphere analyzer tool and iostat show me 100% busy with max throughput near 40MB/s; service time is between 120 and 160 ms let's imagine) ...
A ultrasparc III comes with 8MB l2 cache and 64K icache and 64K dcache and a T1 comes with a 3MB L2 cache shared by all the hardware threads and 8K icache.

The way Rman is working is ressemble a single threaded application. pstack gives me 11 threads but onlu one is doing processing and others are doing I/O ... I got lot of paging activity too but no swapping !
