There is no good reason to limit the trace buffer to 2GiB on a 64bit system. Adjust the types of the relevant parameters.

Wow it's going to take a very long time to transfer that much data over your network.
Thanks for reviewing.
I am writing files with the traces to the mounted file system.
I activated traces in lib/efi_loader only and found several hundred thousand function calls just to start Shell.efi which ended up in exceeding the trace buffer. This is why want to lift unnecessary restrictions.
What I still need to write is a script to analyze the traces to calculate the gross and the net time spent in each function.
