The number of characters has no effect on speed. There is no reason why <w:r> is faster to parse than <text:span text:style-name="T1">.

I'm sorry, Daniel, but I find that hard to believe.

I have a file that is strictly text, numbers, and dates. Seven columns by 63,260 rows -- no formulas, no formatting. Importing as csv takes a few seconds. Converted to ods it takes *much* longer to load -- around 30 seconds or so.

What makes you think that the reason for the slowdown is because OpenDocument uses verbose tags instead of hard to understand tags? The size of the tag has essentially *zero* effect on speed. The slow down is because of the additional steps in compression, XML parsing, and the fact that OpenDocument files contain more information than CSV files.

You can't just compare CSV vs OpenDocument and conclude that the problem is the size of the XML tags. That's plain silly.

I just don't understand why it takes over 80 characters to describe a 4 character text value in a cell with no formatting:

* It's XML.
* Long, descriptive names help ensure correctness.

You're not going to convince me that couldn't be usefully abbreviated in some way and that all that doesn't take cycles to process.

Of course it "can" be abreviated. What I'm saying is that abreviating it is not going to give you the benefit that you think it will. It will not speed up parsin, it will not make the file load faster. It will save disk space, but I doubt that disk space is the primary concern for most people who have documents.

I "get it" about ODF, Daniel, I really, really, do. I'm a supporter. But that doesn't mean we can just pretend that disadvantages don't exist.

Every decision has disadvantages. But the ones you pointed out are ficticious. Instead you could complain that a larger file affects bandwidth and XML parsing slows things down. At least those are real disadvantages. But saying that the size of the XML tag makes the file slow to load is not terribly valid.

Cheers,
Daniel.
