The memory throughput is a key factor for the performance of a computer.|
For many applications, ranging from games to server applications as databases, the memory throughput is the limiting factor.
Most applications rely on the standard glibc routines for memory transfer. Some applications like for example MySQL try to improve the memory throughput by using own routines.
Looking at Linux and the performance of standard glibc functions on PowerPC shows
that Linux is currently not using the potential of the PowerPC at all.
Most functions like memcpy do not even achieve 50% of the possible PowerPC performance.
