[Python] Threadsafe or not?

[Kaan Soral]

I think my requests are lightweight.

I have enabled threadsafe a long time ago but my QPS values for Instances are 0.1 0.3 1.4 etc
Very low

I also have a lot of instances like these, 10s of them ( min_idle = 1 )

Is there anyone who can confirm concurrency in Python?

(I think my regular requests should use 0-3mb of ram, but I have no way of testing it, how can I test it? )

The Python 2.5 runtimes does not support concurrent requests. The
Python 2.7 runtime (currently experimental) does.

Cheers,
Brian

Like I mentioned in my post, I've enabled threadsafe, so you can deduct that I am on 2.7

I have also tried F4 instances today, but although I had 12 instances when I checked, QPS values was around 3-5 and memory was around 90's on all instances
(max 256 but all instances were using 80-90)

So I don't think concurrency is used much

To be clear, I think we are highly overcharged

Actually, you can set "threadsafe: yes" in Python 2.5 as well so that would not be a safe assumption.

There are know issues with using concurrent requests with Python 2.7:
