PK3 Compression [Solved]

[Overdose]

When pk3 files are read and loaded do they get decompressed? If so, would using a less aggressive algorithm help increase map loading speed? In other words would using the "Fast" setting instead of the "Ultra" setting, in 7-zip, help decrease loading times?

If you like having an invalid pure checksum, sure

Regardless of pure, its an interesting point.  Would using zero compression have a speed up?
If so, then there's a good argument for doing it, both for 1.2, and for maps.

Does that matter if the server is already hosting my files?

the pure checksum only applies to files inside the pk3, not to the pk3 itself. repackaging a pk3 with less/no compression will help loading times a little at the cost of disk space.

Ah, my bad.

That's fantastic! Disk space is cheap these days, I'd rather save a few seconds than a few megabytes.

At todays processor speeds you might save zilch to one second - at most. Someone should try to measure it.

It could even take more time, as it has to read more off the disk, and disks are massively slower than the processor.

Hmm, I need an SSD so I can really test it.....donations anyone?
