Do you know where your CPU is spending much of its time? It looks like a job for OProfile. Support for e500 exists in 2.6.x thanks to the fine folks of Freescale. We appreciate their involvement in OSS community. >To check the performance, I used the Dhrystone 2.1 benchmark I like the lmbench microbenchmark too.

Will the SPE enhanced C library calls will be integrated in Glibc one day? Regards, Stephane
