I owe you a beer for the offset and length args. Thanks!

Cool! That would make a sweet example of Clojure is fast at primitives.

Cool!
I did some quick-and-dirty benchmarking of it this afternoon (GMT+2)
and got between 50 and 70 MiB/s on my machine. The Apache
implementation used for comparison by the unit tests came in at
between 30 and 40 MiB/s. Impressive.
I've since seen perf_base64.clj go in, though I'm not clear
I see about a 50% increased throughput over apache commons-codec as well. I
use the perf-base64 ns generate input data and output timing files to keep
track of changes to the performance over time, lest a regression creep in.
I'll add some documentation if you want to play with it.

I've already figured out how it works and have found the same 2:1
ratio. (This time on my 1.4GHz MacBook Air; The previous tests were on
a 2.4 GHz Core2Duo running Linux.)
When I did the quick-and-dirty benchmarking this afternoon I used
larger random inputs (1 to 8 MiB) allowing me to calculate

works.

transform this to base64 using the
Apache Commons library, I get the same result as above. But when I try
to do it with clojure.contrib.base64, I get a slightly different
string. It's quite possible I've misunderstood the
clojure.contrib.base64 API (in which case enlightenment is welcome!),

The original clojure.contrib.base64 was little more than an exercise. This
is the kind of thing that Java libraries do well; don't see much point to
rewriting in Clojure unless somebody clever can make one that's actually
*faster* than the best Java lib.

I use Base64 encoding a lot and the slow implementation is hurting a
lot. It's slower than Sun misc encoder/decoder
and that one is very very slow. I was using Sun's implementation a bit
and it took 80 seconds to encode a 56 MB file.
Then I found this: http://migbase64.sourceforge.net/

This is already possible, if you're using leiningen:
put the file in src/util/ and compile, you can now call it as usual.

Hi,
may I ask an heretic question?
When there is a fast migbase64... why not just use that one?
It was always promoted to use existing Java libraries where it made sense.
Or is clojurescript now changing this stance?
Sincerely
Meikel

This actually introduces an opportunity for a much larger set of utilities.
clojure.data.crypto
base64 is part of this idea anyways, and putting it in place along with
nice wrappers around the messy java crypto bits I think could provide a
significant win. I have had to do this several times
Just wanted to add the Apache commons codec has a base64
encoder/decoder. With a quick test I was able to encode a ~100MB file
in 2.3sec. Example code below:
In leiningen: [commons-codec 1.4]
(require '[clojure.java.io :as io])
(import '[org.apache.commons.codec.binary Base64OutputStream])
Sure, I can use that file. This DIY attitude doesn't benefit the
beginners. I can add and use that java, but 90% of clojure users will
use the clojure contrib function and 9% will use faster sun encoder,
because people don't know that Sun's implementations are slow and that
better ones are
I threw a base64 encoder together a while ago when playing with the new
primitive stuff. Interesting to note that it is faster than the one in
Apache commons-codec.

Whatever works best for you.

I won't personally need that. Plus, this is the kind of lib where the code
