Description Toni Asensi Esteve 2020-08-26 20:44:17 UTC

SUMMARY
When entering and browsing big 7z files: users experience too long delays.

STEPS TO REPRODUCE
1. Creating a big 7z archive, e.g.: `7z a /tmp/test-big.7z /usr/bin`
2. Entering the archive, finding too big delays then (and also when browsing the archive).

ADDITIONAL INFORMATION
Those facts may help: 
- When noticing a large delay, if e.g. `htop` is executed, then it's seen that a `7z -y t` [...] process is using a lot of CPU. When the large delay ends, that 7z process is not seen using e.g. `htop`.
