I noticed that if I had 139 reference assemblies (in a solution memory), I ended up calling the Assembly.Load for 897 times. This is because so many assemblies have the same references like System.Memory, System.Xml, System.Buffers, System.Threading.Tasks.Extensions, ... And the code said "load all reference assemblies". Simple fix: Check already loaded reference assemblies before trying to call the slow Assembly.Load again.
The sourceAssembliesTable_ is a ConcurrentDictionary to ensure thread-safety. However, instead of code using it in thread-safe way, it was used by double-lookup. So that is fixed to actually use it properly. (It's role is to be used as a guard to sourceAssemblies_ array, which is manually lazy-loaded from the queue.)
