[sword-devel] Determining the repository a SWModule belongs to

[contact at tklein.info]

Hi,

For now I'm thinking to store this information (Repository of a  
module) in my own application-level persistence layer.

However, I'm still wondering about the performance of  
InstallMgr::getModuleStatus.
It's not a big issue on current desktop PCs with fast SSDs. On my  
Windows tablet, though - it takes ~3s to call this function using the  
"eBible.org" repository. When calling it for all repositories to  
gather a complete list of modules, it takes ~6s on my Windows tablet.

I guess the function walks through all the module files and a long  
list of files just takes its toll ... Is there a possibility for a  
performance improvement, though?

Best regards,
Tobias
