Hello, I am using the variantconfig.llb for saving/loading configuration files. Unfortunately these configuration-files got very huge: 10.000 lines or even more, having hundreds of sections. Loading these files takes 15-30 seconds. The workflow: - getting all sections with "Get Section Names.vi" (is very fast) - a for-loop is using "Read Section Cluster_ogtk.vi" on each section Name (using Profiler, I can see that this uses the most amount of time). Depending on the section name, I am selecting the cluster type. Do you have any hints, how I can speed up the process? Thanks!
