I have a quite powerful server, how many threads can the app handle in check+post mode without causing problems with missing sites or getting hung up ?
It all depends on what you call powerful. Try something like 100/100 and launch a web page to see its loading time. When the loading starts to slow down, you have to lower the threads.
I just use for scrape, check and sent.open 1000 thread scrape ,check and sent No upload list. Because no many operation. Just let this software scrape check and sent only

I am assume your basing this on your IQ ?
really 1 thread ? to sort through 5 million urls ?
For posting, I use 500 shared proxies and 500 threads.
I've found it depends a lot on the CPU of the VPS.
The software is 32-bit, so it won't use more than 4GB of RAM anyway.
