Work units crunch faster, better benchmarks, etc...
That is just a contest of compilers, compiler options, and what CPU and
system architecture you have.
You'll find significant variation across the projects depending on both
OS _and_ what hardware you happen to be running. This gets more
complicated when you also look at what optimised clients are available.
An old example is that of the old s@h boinc clients just before enhanced
came out. The Linux clients were slower than the Windows clients, until
a few optimisations later gave them something like a x6 speedup!
And there is the Intel compiler "default" whereby the code generated by
the Intel compiler tests whether the CPU is an Intel CPU and disables
certain optimisations for all other CPUs regardless of whether those
CPUs support the optimisations or not... This has only recently (last
few months) been worked around by the s@h optimisers group.
All can change!
