pmaw: slower than psaw for me

Hello,

Thanks for v0.1.0!

I just tried it and for me it was slower than psaw. Below is a standalone that compares the completion times for both. Result: pmaw took 5m16s and psaw took 2m42s.

Am I doing something wrong?

from psaw import PushshiftAPI as psawAPI
from pmaw import PushshiftAPI as pmawAPI
import os
import time


pmaw_api = pmawAPI(num_workers=os.cpu_count()*5)
psaw_api = psawAPI()


start = time.time()
test = pmaw_api.search_submissions(after=1612372114,
                              before=1612501714,
                              subreddit='wallstreetbets',
                              filter=['title', 'link_flair_text', 'selftext', 'score'])
end = time.time()
print("pmaw took " + str(end - start) + " seconds.")

start = time.time()
test_gen = psaw_api.search_submissions(after=1612372114,
                              before=1612501714,
                              subreddit='wallstreetbets',
                              filter=['title', 'link_flair_text', 'selftext', 'score'])
test = list(test_gen)
end = time.time()
print("psaw took " + str(end - start) + " seconds.")
