Should I keep running my old projects as Active, Or just Verify

Greetings, friends.
Wondering if I should keep running some of my oldest set of GSA projects as active…and not just set to Verify only…
I mean those oldest projects where I just link to my money site directly with SER.
I don’t think I need to stop running old projects where SER creates links at T2 T3 .. .. just those pointing RIGHT at the  money site.
…and JUST those projects, of course, that I have newer replacements for with my own T1s, either on PBNs, a few legit listings, and various social media and other content platforms, and hopefully some authority links.
Is it ever OK to link directly to a money site with SER?
I have Asia Virtual Solutions active, blog comment, directory, forum, guestbook,Image COntent, Microblog, Pingback, Referrer, RSS, Social Bookmarks, Trackbacks, Web 2.0, Wiki running.
I also have a separate set of older projects that post to anything that will accept an article pointing at the money site. The articles are OK. Spun, hand-written, reviewed spintax for accuracy. On those I have Asia Virtual Solutions (projects to MS that use articles), articles, blog comments, pingbacks,referrers, social bookmarks, social networks, and wikis that use articles when posting.
This is how I chose to set up older projects. Are *either* the first set of projects, or the second that use articles,  appropriate as a T1 pointing at  a money site? And if not, what SHOULD I be using SER-generated backlinks? I’m *SURE* some will suggest SEREngines. I’ve haven’t used SEREngines since the last version, so if someone could explain I would very much appreciate it. Trying to do SEO right, finally. No more continuing poor practices that are just from a time I didn’t know better.
Should I *NOT* have been doing this? Is it considered “spam practices” by Google? At some point, I came to to understand that T1s should be stable and basically be legit. Is it OK?

alternating between projects & dont remove urls

alternating between projects
when i looked before im sure i saw a way to alternate between projects, i.e. turning projects
on & off for a set period, (so you have less projects running at once so it does not overburden the system)
but when i looked again i couldnt find it.

i thought it was under
main admin screen>options

but looked a few times & couldnt find it, does anyone know where this is ?

dont remove urls

under
project>options

where it says
“dont remove urls – check hint”
what does that mean exactly – does it mean it wont remove the urls when it reverifies them ?
i read the mouse-over text but was’nt sure what it meant.

& “remove after 1st verification try” is greyed out & cant be selected.

Reseting GSA SER keeping projects because high usage of CPU e RAM

How to reset the GSA SER in relation to memory usage and keep only the posting settings in general and the program?
My GSA SER has done a lot of submitted and verified and is now out of memory and with a lot of CPU usage. I would like to keep the projects but reduce the memory and CPU usage. I am currently running on a VPS with 5 Core and 150GB of SSD.

Attempt to merge 2 small fresh projects leads to freeze of GSA SER

Hello Sven,
I have tried several times, to make all projects Inactive, GSA SER is Stopped, no Threads is recognized on the status bar. I have also reset the Submitted records, and projects just keeps Options and Verified (105 and 130) to make projects for merge smaller. No matter what, anytime I try it, GSA SER got frozen. At the moment of trying is running only GSA SEO Indexer,  CapMonster, GSA Proxy Scraper and DropBox application, that feeds GSA SER by fresh lists.
Beyond mentioned apps is yet ran. I have set in all GSA apps count of threads to 20, however neither like that it have no possitive impact.

Is there anything else I can do, not to make GSA SER freezing all the time? That leads me to kill it in Task Manager and start it again.

My HW config is following: Intel i3-7130U @2,70GHz, 12GB RAM DDR4, 1TB M2 NvMe, 500Gbps WAN
System resources are following: 12%CPU, 35%RAM, 0%HDD, 0%LAN. 
My OS is MS Windows 10 PRO 64-bit. The machine is completely dedicated just for purpose of link-building.
Thanks for Your answer.

Michal

How should be GSA SER projects efficiently arranged to create more links?

Hello Sven,
is it better to create one master project and duplicate it aside (lets says 5 times), or create master project (already having approx. 19900 verified links for a few months) and create 5 Tiers below it? I have recently purchased here on Your board annual DropBox subscription with links refreshed every now and then, but DropBpox fights with GSA SER for system resources. Therefore I perform projects to reset some email cache, unify articles to keep only 1 finespinned and so one. My VpM falls no matter how I did it to @ 0,23VpM in a while.
You helped me some tine ago resolve freezing of GSA SER because of houndreds of e-mail addresses, that were kept in RAM. So now, I use for master project just 1000 of them, and they are shared to its Tiers. Now, highest file size in the folder is master’s file (.statics @ 25MB).

Any hint would be appreciated from You.
Thanks,
Michal
