Re: [PROPOSAL] default MAXMEMFREE value

This is a double send from last week (look at the date).

It was probably lost on a queue somewhere for a week.

Anyway, that proposal did not fly.

I will try to get memory/performance data on my Linux box by the end of the week.

As a possible solution for NetWare, we will put the MAXMEMFREE directive

within the if statement of the MPM.

Thanks,

JJ

MAXMEMFREE fixes were checked in the 2.1 tree last week for most of the MPMs

(except Win32). A back port has also been proposed.

I will like to propose insertion of the MAXMEMFREE directive in the configuration file.

I am suggesting that 100 (KBytes) should be used as a default size.

Used within the MPMs, it controls the maximum free memory hold by each running

process/thread and scale down APR memory foot print when bucketing huge files.

Running load test on a 4 CPUs server with NetWare is showing 2 things:

1- MPM-APR allocated memory could now be controlled whatever the

data size going through the filtered I/O system.

2- The performance hit is minimal (less than 1%) using MAXMEMFREE set to

100 or higher in my test environment (Running caching modules with few files of

529 KB size and a short refreshing interval). APR memory footprint with 250 threads

is 82 MB in that case.
