Want keepstore to publish performance metrics:

• Time to first byte from backend
• bytes/time binned by different block sizes (eg 0-4 MB, 4-16, 16-32, 32+ MB) and for all block sizes

Want keep-web to publish metrics

• Time to first byte from keepstore
• bytes/time binned by different block sizes (eg 0-4 MB, 4-16, 16-32, 32+ MB) and for all block sizes

Designate an AWS test environment and conduct tests to get baseline measurements of timing with our current code.

• time to first byte on a file
• bytes/time to read file
• bytes/time to read multiple files
• tests for small (<32 MB), medium (32-64 MB) and large files (>64 MB)
