I created setproperties.xml:
<project xmlns:ac="antlib:net.sf.antcontrib">
<ac:for param="n" end="9999">
<sequential>
<property name="[EMAIL PROTECTED]" value="@{n}" />
</sequential>
</ac:for>
</project>
and build.xml:
<project>
<import file="setproperties.xml" />
</project>
I ran the test three times each on Ant 1.6.2, Kev's
1.7.1 RC, and trunk. The property results are:
162Timings1: 306.0 ms 27.4% 10000x property
162Timings2: 294.0 ms 26.0% 10000x property
162Timings3: 308.0 ms 27.3% 10000x property
171Timings1: 278.0 ms 24.9% 10000x property
171Timings2: 285.0 ms 25.5% 10000x property
171Timings3: 273.0 ms 24.5% 10000x property
trunkTimings1: 278.0 ms 22.7% 10000x property
trunkTimings2: 267.0 ms 21.8% 10000x property
trunkTimings3: 280.0 ms 22.9% 10000x property
So, while I haven't even checked 1.6.3, 1.6.5, or
1.7.0 (the past is the past), it appears that both the
impending release and the trunk outperform 1.6.2.
Surprising, actually, but given that this is the only
noise I've seen on the thread I'd say that puts us in
good shape to commit. :)
