> Going from HDD to ramdisk only got me ~10% gains so I imagine SSD would be somewhere in the middle, for me, not worth the extra $$.  This seems odd to me as I'd have picked big project compilation as being a particularly IO-heavy workload but clearly it's not.

Or you have a bunch of RAM spare and Mr Kernel is doing a bunch of
caching as you are reading and writing the same files all the time.
I'm sure someone here will know how to turn of caching so that you can
do a "better" test?

> So who's got an SSD, what's your workload and what kind of performance gains do you see?  Does anyone have a good home/office/workstation use case for SSDs or is it more limited to, I donno, big databases or large media streaming servers or something?

I do! :)  I like.  I use them for system disks on Cluster machines (a
20GB /tmp predominately for temporary files).
