<pre wrap="">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.<br>
<br>
Still - an option to reduce the memory footprint, when the
additional data is not needed, would be nice.<br>
<br>
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.<br>
