I am running Scrapyd and encounter a weird issue when launching 4 spiders at the same time.

I already have these settings for Scrapyd:

[scrapyd]
max_proc = 10

Why isn’t Scrapyd running the spiders at the same time, as quick as they are scheduled?

    I’ve solved it by editing scrapyd/app.py on line 30.

    Changed timer = TimerService(5, poller.poll) to timer = TimerService(0.1, poller.poll)

    EDIT:
    The comment below by AliBZ regarding the configuration settings is a better way to change the polling frequency.
