Unreal Engine 3/4 and lolzx Compressor

[78372]

Here is what happened :
There was 34.6G of data
First I used dlz
Speed was 180kbps
I think dlz has entropy check because sometime it was 7mbps (copy) and sometime as slow as 180kbps(lowest), 5%/h.
Then I tried your lolz settings with 128m blocks on some normal data just to test.
It was better than dlz, far better than lzma and 380kb/s speed.
But also remember, my data size is 36.4G, so it asked for 33h because sometimes speed slowed down and sometimes increased.
Then I turned almost everything off in lolz and used the lightest settings.
The ratio was even worse than lzma.
Then it asked for 14hours.

Well at last I understand that my *CELERON* pc isn't going to handle these things at a decent speed, I must upgrade.

That is almost certainly because of bursting. It happen also for example with xnlz <stdio> through FA, it load data of block size to memory = during this time speed in FA GUI show 100+m/s, then it start deceasing as it actually process the block and then process repeat again. Dlz is likely simply copying next data to block for processing and show burst speed to output.

Also it could be speed of scanning rather than processing, lolz btw also vary between 2-7mbps.

Finally, 7mbps cannot be a speed of raw copy, that would be too slow for such thing.

Try it on smaller size like 1gb and compare *final* compression time between dlz and lolz(but also ratio). Then you get best picture. If you get similar ratio but visibly better time on dlz then you may be right, but this is highly unlikely and I would be surprised. If anything, I would expect lolz to give you better both speed and ratio - with settings I provided.
