Home / Search runs too slowly

Hello,

I’m currently using SumatraPDF version 3.2.0. Among the files I routinely open, search runs very slowly in 20-30% of them. Sometimes the UI even gets hung. The most recent version of Adobe Reader actually runs the searches much faster, without any delay in the UI.

Is there any way to solve this problem?

Thank you.

I think there were some speed improvements after version 3.2 so try the prerelease version
