Hi Gambit List,
What's the quickest way of reading a file from disk into memory?
I tried 'read-all' with 'read-line', but unfortunately even with
compiling I get an order of magnitude worse performance than doing the
same in python.
I'm using the following code, compiled using gsc and gcc -O3, and I get
500ms to read the 'bib' file supplied in the bench.tgz package.
----------------------
(define (f)
(call-with-input-file "bib"
(lambda (p) (read-all p read-line))))
(time (f))
------------------------
In python, the same takes about 50ms
e.g.
for line in file("bib").readlines():
# do something
Is there anything I can do to speed this up?
(I've tried setting
#define ___MAX_CHR 0xff
)
Many thanks,
Phil
