Size vs. Size on Disk??

[Yo Adrian]

I have a directory that contains:

545 KB Size
2.62 MB Size on Disk

Why the huge difference? I'm trying to calculate the bandwidth usage of this site.....I imagine I need to calculate the 545kb, right?

And do you think 545kb is too big for a custom tour?

I am not sure about the first question; but as for what the size for a tour should be it depends - how many pages? are the pages setup to load in a way that keeps the surfers attention, etc.. Basically a good way to check, (if you have the abiltiy to) is load your site thru a dial up modem and ask yourself "would i stick around for this to load if i was waitin to get my rocks off?"

hope that helps - and i hope ya get the answer to the first question as i'd like to know aswell.

I use Dialup. There are very few paysites I have visited where I let the whole front page load. They just take too damn long.

It's a simple 1 page custom tour for a paysite. It's a killer tour that is sure to keep surfers waiting for it to download...

I just don't want to host it myself until I know that it's not an outrageously huge file size.

Disk space used is always greater than actual file sizes because disk is written to in blocks. The size of the blocks is fixed and is determined when the disk is first formatted. When each file is written to disk, the beginning of the file will align with the start of a block and it will span however many needed blocks it takes to store it. The last used block will most likely have left over space that cannot be used for anything else and that's where the apparent discrency in size arises.

Yes, bandwidth is determined by actual file sizes, plus the TCP overhead.

If the tour converts, it's just the right size.

It's not the size of the file that matters, it's how you store it.

545 for one page? normally i would say that is pretty damn big for one page; but then again i haven't seen this particular page. I have a dial up modem as my backup connection - if you want to post the link i can check it out thru that and give you a better opinion. But Hybrid is right - if it converts, dont change a thing

Excellent, thanks for the informative reply
