No idea if this will improve it, but have you tried the following?
t.@member = val

Hi all, I’d like class field access in specific classes to be without
groovy magic, so that it is as fast as possible. I guess this means
disabling runtime metaprogramming for specific classes (or fields).
At first, the
http://docs.groovy-lang.org/latest/html/api/groovy/transform/CompileStatic.html
annotation looked like it might do the trick, as it mentions class
properties being covered. It certainly works for class methods, but
in my testing it didn’t make any difference to class members. Setting
the field “directly” (ie, via t.member below) is still an order of
magnitude slower than using its implicit setter directly (ie,
t.setMember()). Similarly for field access vs getter. That
annotation does not seem to cover field access or assignment.
So, is there a way to make field access as quick as using the implicit
getter/setter? Thanks, Simon.
For example, on my 3+GHz Xeon with jdk1.8.0_66/groovy-all-2.4.3, the
below code gives me:
t.member = val 34.577
t.setMember(val) 3.529
t.with { member = val } 127.922
*package*test
*import*groovy.transform.CompileStatic
@CompileStatic
*class*Test {
String member
}
String val = 'test'
Test t = *new*Test()
*for*(*long*i = 0; i < 100* 1000* 1000; ++i) {
t.setMember(val)
}
*long*time = 1000* 1000* 1000
*long*beg = System./currentTimeMillis/()
*for*(*long*i = 0; i < time; ++i) {
t.member= val
}
println('t.member = val\t\t'+(System./currentTimeMillis/() - beg) /
1000.0)
beg = System./currentTimeMillis/()
*for*(*long*i = 0; i < time; ++i) {
t.setMember(val)
}
println('t.setMember(val)\t'+(System./currentTimeMillis/() - beg) /
1000.0)
beg = System./currentTimeMillis/()
*for*(*long*i = 0; i < time; ++i) {
t./with/ { member= val }
}
println('t.with { member = val }\t'+(System./currentTimeMillis/() -
beg) / 1000.0)
