General performance issues

[spaaaacccee]

There are some performance issues with the usage of the platform, particularly when uploading files. Suggest to take the following actions:

• Separate solution path from ongoing submissions documents
• Cache aggregations to disk
• Isolate read handlers to a separate process so background compute has less impact on basic site usage
• Immediately remove dominated or outdated plans from upload process
