Tried compressing 800MB of data with ZPAQ, set everything to maximum, 520 minutes have passed and it still hasn't finished. Checking CPU utilization and while i'm playing some music, i'm getting up to 3% CPU usage. Hardly any HDD activity. Seriously, no wonder ZPAQ takes gazillion minutes to finish if it's like idling there, doing exactly nothing at all. When i run LZMA2 (with 7-zip), it's properly crunching data, CPU utilization goes very high, but also finishes ANYTHING in a matter of seconds. ZPAQ in PeaZip on the other hand, takes ridiculously long no matter what you give it to compress, even if it's a tiny 20MB thing.
I have an Intel Core i7 920 overclocked to 4GHz (with 8 freaking threads!), 6GB of RAM and a hybrid HDD+SSD storage and all this raw power is idling there, doing nothing. It could finish like 20 times faster if it would use all 8 threads and utilize CPU to at least 75%.
I don't know who's fault it is exactly, ZPAQ compressor itself or the PeaZip, but either way, it makes absolutely no sense that i have all this power at my disposal and it's not being utilized at all. I mean it's actually not being used, because at 3% CPU usage and hardly and HDD blinking, there is just no way anything is being properly processed (compressed). Use the damn CPU and compress the data faster. People might even start using ZPAQ then because it won't be entirely and completely useless like it is now...
