For some time now I have had a setting of ‘5 days’ as the limit for the number of posts to display on my site. My rationale, as in most things, was to limit the number of bytes any individual reader needed to wait for during a site visit (and download).
However, that may be dial-up thinking.
I was playing around with my own site and viewed monthly archive options. Lo and behold, with my 5-day limit, that also translated into that display as well. So, I upped my limit to a full month (31 days) and repeated the step.
Sure, downloads were a little slower, but not truly noticeably so, and I am on an IDSL line (128 kb) anyway! Anyone with anything approaching a modern connection should not have a problem upping post display limits.
Oh, well. My advice to everyone (and I’m likely the last) is to up your blog display governors.
