For the file large_file.txt.gz when tried to parse using the following, it is going to freeze state.

$ iex -S mix
Erlang/OTP 20 [erts-9.3] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:10] [hipe] [kernel-poll:false]

@krishna-goteti I've spend a few minutes trying to improve the performance but none of my experiments fixed this issue. Depending on your use case, you might want to use :xmerl directly :)
