Comparison of lab 2 and lab 3 results:
Avg response time, number of connections, and maximun number of requets per seconds would all decrease for this lab due to more computation and
I/O requests. In lab 2, all the data was in memory and so it was much faster to access. Here we have a sqlite3 database and so there are more read operations from the database rather than from memory.
Memory utilization and disk I/O also increased for this lab. SQLite has a cache and so uses more memory to store that data instead of using disk. There are only read operations and the dataset we are working with fits in this cache system and so there is a very small amount of disk IO utilization and high memory utilization.
SQLite flushes the page cache disk when needed to write.

Lab 3 Benchmarking:

ab command:
ab -n 1000 -c 26 http://ec2-54-160-115-230.compute-1.amazonaws.com/?keywords=computer

Results:

Maximum number of connections before dropped = 26

Maximum number of requests per second (RPS) = 208.59 #/mean

Average response time or latency per request = 124.649 ms

99 percentile of response time or latency per request = 1368 ms

Utilization of CPU = 70%

Utilization of memory = 79%

Utilization of disk IO =  0.1%
