.SH NAME
@IMAGEX_PROGNAME@-optimize \- Optimize a WIM archive
.SH SYNOPSIS
is that every stream in the original WIM will be checksummed, so this can help
verify that the WIM is intact (equivalent to applying all the images from it).
.IP ""
-Note: as mentioned in the README, wimlib generally provides a slightly better
-XPRESS compression ratio than Microsoft's software, while it generally provides
-a slightly worse LZX compression ratio than Microsoft's software. So, you may
-not want to specify \fB--recompress\fR when optimizing a LZX-compressed WIM
-created on Windows with Microsoft's ImageX.
+Note: as of wimlib v1.5.3, wimlib's LZX compressor usually achieves the same or
+better compression than Microsoft's, but is slightly slower.
+.TP
+\fB--compress-slow
+For LZX compression only: spend even more time compressing the data in order to
+achieve a more optimal compression ratio. This will make compression about
+twice as slow and will increase the compression ratio by maybe 1%, if you're
+lucky.
