Hello biogon,
Welcome to the forum.
[Topic moved here, since it's large dependent upon the computer hardware.]
These are some previous topics that cover the loading speeds that people achieve with different specifications of computer hardware, where the bottlenecks are likely to be, and how to reduce them:

However, subsequently it will load from a cached version of the organ, for which loading speeds are likely to be between 50 MB/s and 1 GB/s, depending on the speed of your SSD/hard-drive(s), the speed of your CPU and number of cores that it has, and whether the virtual ranks options are set to load compressed or uncompressed.
With a basic 7200 RPM hard-drive you might get around 60-130 MB/s, whereas with a very modern PCI-e SSD, very fast modern Intel i7/i9 CPU with at least four cores, and loading uncompressed, you should potentially be able to reach 700-1000 MB/s. With a mid-range CPU and a basic SATA SSD you're more likely to get loading speeds in the region of 170-250 MB/s.
You can see the loading speed that your PC achieves by using '
Help | View activity log' after loading the organ, then looking at its '
Sample loader: approx. avg. overall data read rate' figure (if it loaded from cache).
The size of the sample set cache file will be roughly equal to the amount of RAM used by the sample set when loading compressed (since the cache file is always compressed, even if you load the ranks uncompressed). Hence if you have a PC (with 32+ GB of RAM), and you loaded a sample set that used 24 GB of RAM uncompressed, and your PC was extremely fast and could achieve loading speeds of 1 GB/s then the sample set should take at most 24 seconds to load (probably closer to 15 seconds, since the cache would be compressed).
If you select the 'Custom' option in Hauptwerk's installer you could choose to put Hauptwerk's '
Internal working data' (which are the speed-critical sample set cache files) and the '
User data' (speed-critical settings files) on your SSD, whilst keeping the '
Sample sets and components' (mainly not speed-critical, but very large, raw sample set files) on your 7200 RPM hard-drive. The '
Installation: background information: Planning installation locations' section in the main Hauptwerk user guide (on the Help menu in Hauptwerk; pages 18-19 in the current v4.2.1 version) covers that in more depth. You could just re-run the installer and it should move your existing installation accordingly. (It's always a good idea to use '
File | Backup ...' first, just in case anything goes wrong when moving the data.)
