When I compress a 800MB tar archive into a 7z under Windows 11 (AMD Ryzen 7 4800H), NanaZip takes about 4 times longer than 7-zip. NanaZip uses only about 20% of the CPU. The current version of 7-zip uses over 95%. I have tried the NanaZip and the NanaZip preview. It also doesn't matter if you install from the Microsoft App Store or if you install via the installer.

NanaZip can uses most compute resources from CPU if you see my screenshot.

我遇到了同样的问题。如果是在文件夹上右键选择“添加到‘xxx.7z'"会出现这种情况，CPU占用大约20%，内存能用完；如果是选择”添加到压缩包...“，然后再确认（不修改压缩选项）则不会出现。原版7-zip 21.07没有这种情况出现。我的机器配置R5-5600G 16G内存 Win11Pro 22000.593，压缩Office Tools和下载的Office安装文件时遇到的。

Do you have anything under HKEY_CURRENT_USER\SOFTWARE\NanaZip?
