Downloading LLama2 and Other LLMs Running So Slow

**Describe the bug**
I noticed that downloading and running LLMS such as llama2 and others are very slow. It takes lots of time in my local system to download the model before generating completions. Typically it is faster on Collab with quantization technique.

**To Reproduce**
Steps to reproduce the behavior:
1. Write any valid LLM-VM completions generation codes.
2. Select 'llama2' as 'big_model ' parameter.
3. Run or execute your code.
4. See error

**Expected behavior**
The whole process of downloading LLM models, shards, checkpoints,.. and completions processes should be faster . Perhaps everything should be done in 3-6 minutes. It takes average of 3-4 minutes in Collab.

**Additional context**
I am not running the code from Notebook, yet to try it on jupyter notebook. Rather I am running from command prompt that comes with PyCharm IDE.
