The waiter, hmm, something is not right in your case. For just 10 dictionaries, the startup should be pretty fast, even on Windows.
Please check that your dictionary path setting is correct and doesn't include folders with deep nested sub-folders or something like that (for example, folders with huge about of various files).
Ideally, all 10 dictionaries should be placed in a single folder, and that folder should be set in the dictionary path settings, without recursion into sub-folders. This should be the fastest way.
