The top left arc is cut off in the middle! Have since commented out (define

Thanks a lot George, for this insightful reply.
Your idea about FFI explaining 95% of the overhead looks good... but i wonder:
in this case, shouldn't we also see a high cost in bind-prepared-statement
alone?
(sorry for my sketchy english)
Thanks again,

I'd like to typeset some Javascript code in a way similar to what pict/code

doesn't quite work because of the reader adding whitespace in various places.

I use the `java-lexer` package to typeset JavaScript code:

To turn those into picts, you can use `codeblock-pict` from

I subtracted the two timings, which should get rid of everything but the query
time, and gives about 30s for raket vs. about 5s for perl.
Good catch! I just pushed a fix.
Thanks!

Gregor shares the near-universal disdain for UTC exhibited by operating systems

Seriously, though: Gregor doesn't keep UTC time, so there are no leap seconds.

it.
