I am experimenting with running racket natively on Android to compare with my
current embedded Chibi scheme implementation. It would be convenient to just
leave racket as a separate process and communicate over sockets/pipes so it
exactly mimics my remote development case.
The startup time to run a trivial console program is very long. A one line
program with #lang racket/base takes over seven seconds:
root@trlte:/mnt/shell/emulated/0/Oculus/racket/bin # time ./racket cmdline2.rkt
cmdline2.rkt <
line 1
line 2
line 3
line 4
line 5
line 6
line 7
line 8
line 9
0m7.96s real 0m7.04s user 0m0.65s system
My first test, which still had the default #lang racket, took almost a minute
to start:
root@trlte:/mnt/shell/emulated/0/Oculus/racket/bin # time ./racket cmdline.rkt
cmdline.rkt <
line 1
line 2
line 3
line 4
line 5
line 6
line 7
line 8
line 9
0m54.16s real 0m48.68s user 0m4.83s system
On a PC, it only takes a fraction of a second. This was on a Note 4, which
should not be 100x slower than a PC. Could it not be using the compiled
library bytecode somehow? I didn't see any command line options for verbose
output on startup, is there any way to force some extra information?
