How to increase a number of daily links and LPM with global site lists?


Hello,
i have a question.
Is there any way to increase a number of daily links that GSA SER creates from global site lists? I use lists from https://www.serpowerlists.com/ and they are great. But usually i have only about 200-300 verified links per day and LPM is 0,81. I do not set any limits on daily links in settings:

All filtering options are unchecked:

I connected dropbox folders to GSA SER:
Identified – Contextual_URLs
Submitted – Top_Tier_URLs
Failed – Verified_URLs
https://prnt.sc/uz9y63
Checked Identified, Submitted and Failed and Use URLs from global site lists if enabled:

I run GSA SER on Windows VPS with 4 core and 8 GB RAM at 40 threads with rotating dedicated proxies from https://stormproxies.com/rotating_reverse_proxies.html (40 threads proxy package), 1 catcha-ll e-mail from catchallboxes.com and Xevil for captcha recognition.
For some reason GSA SER runs mostly at 7-10 threads instead of 40 in settings:

CPU and RAM are not higher than 50%.
I decided to check how it will change the situation and directly uploaded target URLs into the project (Import target URLs – From site lists – Identified, Submitted and Failed). GSA speeds up to 40 threads, LPM is still low:

In total its a big number of targeted URLs (713K URLs), but i still have about 200-300 daily links from uploading targeted URLs.
Sometimes i see message “No targets to post to (no search engines chosen, no url extraction chosen, no scheduled posting)” in my projects:
https://prnt.sc/uz9q76
At the same time dropbox folders with site lists are updating every few hours.
If i click “Show URls – Show remaining target URLs”, it usually shows 0 URLs, or 8-10 URLs.
Is it possible to solve this problem? Am i doing something wrong?
Thank you!
