Hi,
(as far as i can tell after a quick peek at the code and some debugging)
It looks like there is a bug w/ AxKit::run_axkit_engine() and/or
Apache::AxKit::Cache::_get_stats()
run_axkit_engine() wants to create a .gzip cachefile when AxGzipOutput is off.
When AxGzipOutput is off the .gzip file is never made and _get_stats()
returns w/ !$self->{file_exists} effectivly disabling delivering cached copies.
With AxGzipOutput enabled both files are created and appropriate cached copies
are delivered as expected.
I haven't decided for myself a best fix except for just enabling AxGzipOutput.
So, I reran hello/bench.pl w/ AxGzipOutput On and sped axkit up quite a bit.
attached are some diffs and a couple of 1 sec bench.pl runs. Would be
interesting to see how axkit compares now?
Thanks,
Ed
