This is a performance measure of the basic non-numeric processing capabilities and for Linux systems often about twice the basic clock rate in ``MHz'' as available by Sys.cpuinfo()["cpu MHz"].

Sys.ps, etc.

Examples

cbind(Sys.cpuinfo())
Sys.MIPS()
Sys.MIPS() / as.numeric(Sys.cpuinfo()["cpu MHz"]) ## < often about 2
