Racket 5.3.1 is amazing.
Compiled, it runs 20 update queries per second on a local SQL Server
data store, whereas 5.3 ran, at best 5 queries per second. Both figures
inclusive of garbage-collection. Also it is stable (5.2 and earlier had
memory leaks, probably from mysterx library)
I don't have a basis for comparison, but running the web-server, I'm
getting 300ms request-response cycles across the network, whereas I was
seeing 900ms-1200ms cycles with v 5.3.
Numbers are with old development hardware and I haven't spent any time
profiling the code.
Extremely, extremely impressive.
Thanks very much.
