Hi All,
I am getting a serious memory issue with my Apache webserver.
Initially I was allocating buffer from by using apr_palloc from the request
pool assuming the allocated memory is going to be released but not sure what

I then tried with own malloc

Thank you for making this clear. My vote is for choice #2.
I'd also tend towards a httpd-test Product

Hi Dirk-Willem,
Can you please clarify your mentioning the bucket-brigade footprint?
Are they so slow they make memory-based cache no more efficient then
disk-based one? Or the opposite: sendfile() works so well that serving
content from memory is not any faster?

Hi all,
On a number of occasions recently I have run into the need to run some
kind of garbage collection within httpd, either in a dedicated process,
or a dedicated thread.
Attempts to solve this to date have involved setting up of external
tools to try and solve garbage collection

Is this hook documented anywhere?

A small correction: I meant writev() calls instead of sendfile() when
working with small-size buckets.
The filter I'm developing provisionally splits the supplied buckets
into relatively small buckets during content parsing. It then removes
some of them and

Of course, it will not work exactly as I have said because we have to take
