Aegisub loading subs and video is slow. How to make faster?

Unread postby Someone » Sun Feb 12, 2017 11:49 pm

Anything can be done to speed up load of subs (parsing matroska) and video in aegisub?

It seems unusually slow as I just got a faster computer but it loaders slower than my older slower computer.

I think video loading is generally I/O bound rather than CPU bound. I tried copying a 2 GB MKV file to my system drive (SSD) and then loading that for video in Aegisub. It didn't reach a full CPU core in utilization.

On the other hand, none of this has really been optimized and I don't think anyone has even looked at the performance characteristics of any of this code before.
Do not PM me asking for help with Aegisub, Automation, karaoke or anything like that, I won't reply.

Seems to be files I downloaded to computer via torrent load slowly, even when torrent client is turned off.

Files copied from different source or duplicated from original load very fast.
