Re: [rrd-users] filesize using 32-bit vs. 64-bit

I am waiting for cross platform, but for I changed to using the i386 version of collectd on our x86_64 systems, so that I have a single place to graph.

Hi Ulf,

the file size difference comes from the padding differences between
32 and 64 bit ... once I introduce the cross platform file format,
all architectures will take the same (manybe slightly bigger) size.
