site_archiver@lists.apple.com Delivered-To: installer-dev@lists.apple.com -pmb Hi: I have a software updater application that downloads Packagemaker packages from a server and launches these one after the other using the commandline "installer" tool. I asynchronously monitor the status of the package installation in my application and update a progress bar in the UI to indicate install status. This application has to work in 10.3.9 and 10.4.8. Issue: ====== I am observing that the install time in 10.3.9 for my updater application is significantly longer than than the time it takes for the same operation to occur with the same packages in 10.4.x. On further investigation, I discovered that the additional time is being taken by the optimization process (I guess pre-binding). It appears that this process is occurring for each package run by the "installer" tool. This does not occur in 10.4.x and later. In scenarios where there are a bunch of packages to run, the additional time taken for this process is noticeably significant. Sometimes, the optimization process takes more time to execute than the install process itself! This time is unacceptable in 10.3.9 when the user has to download and install the whole software suite (I also support reinstall from the updater) that consists of at least 15-20 packages. Is this a known issue/observation ? What I would like to do is bypass having each package installation execute this optimization process. I can perform this separately from my code after all packages are installed. Are there any realistic ways to resolve/workaround this issue ? _______________________________________________ Do not post admin requests to the list. They will be ignored.

Your analysis is correct. The additional time needed in 10.3.x is due to update_prebinding. Unfortunately, there is no way to skip or coalesce this step in 10.3.x. Improving this was one of the major features of the 10.4 installer. At 9:42 AM -0700 10/24/06, Steven Lobo wrote: Steven This email sent to site_archiver@lists.apple.com
