Hi
I have an application of about 10.000 LOC using Guile/GOOPS with
performance problems. I found a way (thanks Ludo!) to run it with
and without GOOPS, and gained a factor of 30 in performance. See
details below.
TL;DR
1) do not use multiple dispatch/define-method: factor 2
2) use plain lists (interface name (types ...) ...) instead of
(define-class <interface> (types ...) ...): factor 5 (another factor 3)
3) use guile-2.2 instead of guile-2.0.11: factor 30 (another factor 5)
Amazing work!! (even faster than V8/nodejs)
Although 3) just upgrading guile and gain a factor of 5 sounds very
nice, it wasn't so easy for me to collect that factor 5.
Using guile-2.2 with GOOPS still in place does not help much (bit
slower when using multiple dispatch/define-method, bit faster whithout
multiple dispatch). So, I had to do 1) and 2) to find and collect 3).
I am considering to use GOOPS for development and run without GOOPS in
production (if the extensive regression test still passes :-)
(Prototyping in Guile and) rewriting it in C++11 would easily give us
another factor 10/20... :-(
Suggestions much appreciated.
Greetings, Jan
The `gaiag' script runs the version with GOOPS, the `g' script uses
plain lists.
$ guile --version guile (GNU Guile) 2.0.11
$ guile-2.2 --version
guile (GNU Guile) 2.1.0.1098-5ded
Using define-method; multiple dispatch
$ time GUILE=guile ./gaiag -l resolve Handle.dzn >/dev/null
real 0m8.128s
user 0m8.100s
sys 0m0.004s
$ time GUILE=guile-2.2 ./gaiag -l resolve Handle.dzn >/dev/null
real 0m9.738s
user 0m9.784s
sys 0m0.048s
It seems that multiple dispatch is a bit slower on 2.2 ...
I rewrote all usage of define-method
(define-method (foo (o <top>) o))
(define-method (foo (o <interface>) (mangle o)))
using match
(define (foo o)
(match o
(<interface> (mangle o))
(_ o)))
and rerouted make from
(define-class <ast> ())
(define-class <named> (<ast>)
(name :accessor .name :init-value #f :init-keyword :name))
(define-class <model> (<named>))
(define-class <interface> (<model>)
(types :accessor .types :init-form (make <types>) :init-keyword :types)
(events :accessor .events :init-form (make <events>) :init-keyword :events)
(behaviour :accessor .behaviour :init-value #f :init-keyword :behaviour))
(make <interface> ...)
to the non-hygienic (thanks Ludo! ... hygiene-clue-bat appreciated)
(define-syntax make
(lambda (s)
(syntax-case s ()
((_ type args ...)
(with-syntax
((m (datum->syntax #'type (symbol-append 'make- (syntax->datum #'type))))) #'(m args ...))))))
(define (make-<interface> . args)
(let-keywords
args #f
((name #f)
(types (make <types>))
(events (make <events>))
(behaviour (make <behaviour>)))
(cons <interface> (list name types events behaviour))))
and
(define <interface> 'interface)
and used SED (ugh) to change
(match o
(($ <interface> name types) (bar types)))
into
(match o
(('interface name types _ ___) (bar types)))
I could use records instead of lists
+ no SED needed, nice and unchanged record matchers
($ <foo> first-element-only) match
('foo first-element-only) no match!
+ more type-safety?
- rewriting the tree is so much nicer with lists than records/goops
(match o
(('interface body ...) (bar interface))
((h t ...) (map foo o))
(_ (foo o)))
- printing is simply pretty-print
- much work, what's the performance impact?
- not used much by schemers?
