Table 5 ‐ 1 lists sample compression ratios and startup times for a Microsoft Office 2003 package that runs from
a local hard drive.
Compression has some performance consequences and can affect the startup time on older computers or in
circumstances where you start the application multiple times and depend on the Windows disk cache to
provide data for each start.
The CompressionType parameter does not affect MSI files. For information about compressing MSI files, see
“MSICompressionType” on page 84.
Examples
ThinApp sets default values for the OptimizeFor parameter and the CompressionType parameter that work
together to achieve maximum memory performance and startup time. ThinApp stores all data in
uncompressed format.
[Compression]
CompressionType=None
[BuildOptions]
OptimizeFor=Memory
You can use this configuration when disk space is moderately important. Thinapp stores executable files in
uncompressed format but compresses all the other data.
[Compression]
CompressionType=Fast
[BuildOptions]
OptimizeFor=Memory
You can use this configuration when disk space is the top priority. ThinApp compresses all files.
[Compression]
CompressionType=Fast
[BuildOptions]
OptimizeFor=Disk
MSICompressionType
The MSICompressionType parameter determines whether to compress MSI files for package distribution.
Compression improves performance when opening MSI files and using the ThinApp SDK.
If you create an MSI file during the capture process, ThinApp adds the MSICompressionType parameter to
the Package.ini file and sets the initial value of Fast to compress the file. Decompression occurs at the time
of installation.
You do not have to set the MSICompressionType parameter to Fast when you set the CompressionType
parameter to Fast . Setting both parameters does not increase the amount of compression.
