comment Graphics exported from Mathematica 9 are very large because even standard fonts are embedded
I know this is not a solution within Mathematica, but for those not willing/able to upgrade to Mathematica 10 yet you can use the simple Linux tool ps2pdf, which accepts PDFs as inputs as well: ps2pdf -dEPSCrop figure.pdf figure-nofonts.pdf. This will remove unnecessary embedded fonts, greatly reducing filesize (the dEPSCrop saves the original bounding box).

comment Limit as n -> ∞ for RSolve with Multivariate Recurrence Relation
@DanielLichtblau I tried, but the two Sums remain, regardless of the assumptions. The best I was able to do is get rid of the UnitStep[n-1] from the numerators when assuming n >= 1.

comment Limit as n -> ∞ for RSolve with Multivariate Recurrence Relation
@hftf ...yes, haha. So I guess the answer is just (1/y)/(1/y + 1/x) for a[n]? But how to find that from RSolve...

comment Transferring a large amount of data in parallel calculations
I must say that the "speed-up" from doing things in parallel here, even after the fix, is pretty lackluster. 3.5 seconds to 3.0 seconds? I imagine the speed up would even be worse if one tried to do 4 or 8 kernels...

comment ListPlot with each point a different color and a legend bar
The plotting here is tremendously faster than the accepted answer, FYI.
