Hi all

I'm experiencing weird redis thrash that's causing the test suite to go very long, and smash redis;

1 worker:

2 workers:

8 workers:

Further information:
1030 tests in spec suite
redis 3.2 running in a docker container
ruby 2.7.4 running in a docker container

gems:
rspec 3.9.0
rspecq 0.7.1
redis 4.1.2
redis-rails 5.0.2

Interestingly the cmd/s is fine for 1 worker, but with 2 or more workers it jumps orders of magnitudes into the 10s or 100s of thousaands and saturates the redis instance, slowing everything down.

I am running the commands with the following:

RSPECQ_BUILD=<8 digit randomly generated string>
RSPECQ_REDIS_URL=redis://redis:6379/8
RSPECQ_MAX_REQUEUES=3

for i in $sequence; do
    echo "Testing $i"
    TEST_ENV_NUMBER=$i bundle exec rspecq --worker=$i "$FILES" > /tmp/rspecq_${RSPECQ_BUILD}_${i} 2>&1 &
    pids[${i}]=$!
done
