# Dependencies - UVLoop - python-socks - ssl Most of these libraries do not support windows Solely for checking if a proxy is alive, checks ~1200 proxies a minute with 100 workers, cpu load and memory being negligable UVLoop isn't necessary, but does give far greater performance Theoretically you could run thousands of workers, you would just need to increase the maximum file descriptors allowed Drop the `CHECK_TIMEOUT` if you would like to increase time, this would likely ensure that the less responsive proxies are verified 1000 Workers uses roughly 5% cpu on a dual core, completes checking 10000 proxies in roughly 4 minutes.
