I didn't get the 8%-10% by minifying - the performance gain with
minified vcls is lower.
Just for testing, I removed the part in the vcc_compile.c responsable
for adding scrbody to the compiled object to get the full performance
improvement.
The only thing you have done is remove the memory footprint by a
few kilobytes.
If that radically changes your performance it can only be because
it allows you to operate entirely inside the L1/L2/L3 cache of your
CPU.
That would indicate that your benchmark is so trivially simple that
it is invalid for any realistisk workload with more than one URL.
I haven't said anything different. The test is simple as i already
stated in my very first post.
Still - an option to reduce the memory footprint, when the additional
data is not needed, would be nice.
Btw. the situation becomes relevant, when you have one or only few
resources that are not cachable and will hit much more frequently than
all the other resources.
