Hi, I started using parallelization for my e2e cypress tests in aws code build
, i did setup build spec and given 3 machines to run in parallel, but the thing is when i run all the tests, it took nearly 30 mins build time each(unbearable cost), which includes installing of node modules and server start time in each machine, and got separate cypress json's for machine. how to overcome this, is there any best practice to fix this build time
