I have been operating on linkedin for along time, almost since it started, in parallel I kept my European presence alive even after moving back to Canada from Switzerland in 2010. Linkedin used to be fast (with far fewer features), then became slower and slower over the years even with hardware upgrades. Then MS bought them a few years ago and well in the Freemium space you get to consume lots of adds and a constant "rain of suggestions" from what has become the biggest piece of bloatware on the planet.
I thought it was me, that I was seeing things and being over critical, so I did a few simple System monitor checks via my Linux based OS.
Just for "shits and giggles" as they say over here, I compared the memory use and the first load times of the two, Linkedin vs. XING in their freemium forms to see how they compared.
The score? XING 2- Linkedin 0
Memory 100MB 400MB
Load time 2 Sec 8 Sec.
Platform iMac Dual Intel Core 64Bit 2Gig RAM circa 2009
OS Debian Linux (Peppermint OS) a nice tight configuration that breathes new life into old computers
If you want speed in a non US Biz Contact App running on your browser with the bare minimum of capabilities and a large network of mainly European centric contacts then XING is a no-brainer.
Given the likelihood MS will at some point (like Twitter, Instagram, Youtube) start to censor you posts and make even money off of your data when ever they like (as Anti-trust never seems to apply to MS in north America), Xing might also be a good choice.
If you are starting with a clean piece of paper, and just want to go fast and your fans and friends are just starting out, maybe you all as a group should simply start off with XING.
If you are hopelessly mired in Linkedin there is only one solution. Kill the problem with hardware. Get a bigger faster 6 core computer next time around with 8GB or even 16GB (if you can afford the car-like payments), as MS always designs to maximize and dominate memory use and disk space to maximize sales of Intel and AMD and their OEMs and channels will be happy to sell you a new one. Especially if you are also trying to run IPFS and CryptoKitties in parallel.
Me? I am minimalist, I will squeeze another 5 years of duty out of this well built iMac by employing smart software choices, and by using fewer Brave browser tabs open at once. :)
One should note Apple did in fact, along time ago, lead price/performance for Desktops, as the iMac circa 2009 came with a great super fast screen refresh at 2msec, perfect for browsing, writing and believe it or not running my Qblade CFD runs, all day long without eye strain caused by slower flickering displays of the day. That advantage is long gone today.
Personally, I will look for a used computer when the day comes to replace this iMac Hardware. Hell I still use "spinning rust" for storage.
Maybe in 3-5 years I will have 8GB RAM and Flash that actually lasts 20 years which is what you should get out of computer now a days given how much disposable income it gobbles up, as much as most used car buys these days. By then in 2025 everyone will be running 16-32GB and 6-8 cores of 64bit each routinely while they worry about whether or not they can make the payments. ;)
As for OS choices, there can only be one for me. Linux. There are no excuses now for the desktop, this my 20th year operating Linux on the desktop, The Peppermint OS variant of MINT running a lighter Gnome like windowing system with Intel's microcode support, so I can natively run the NVidia Graphics Card drivers makes a big difference in speed and is what keeps this iMAC alive.
Regarding software choices, IMO paying for software should be the exception, adn the value offered should be exceptional, as paiying for software should not be the rule, as the world has finally fully emraced Open Source in a collaborative development sense.
Sourceforge was the first big enabler of open source, then came Git and all free open source platform services GitHub, Gitlab, now Bit Bucket and more. And now we finally have Garbage Collection a la Rust (programming language) to replace C++ and C. No more memory leaks, because some C or C++, C# programmer mishandled malloc and blew up your mobile phone or desktop when you least expect it.
So the dominance of Java and C++, and even C# is finally going to be behind us, and with it alot of bloatware...like Linkedin in its current form.
My advice to MS and the Seatle/Redmond crowd is they can, for what its worth, start writing your stuff in Rust, it's time, otherwise your collective day in the sun is over.
Finally the only real challenge out there for me is buying a PC without MS Windows or Apple OS for the Desktop pre-installed. The vendors are out there, offering naked machines. Personally such "birthday suit" hardware should include and be sold with open source VM management software and you simply load a VM or two of your choice with OS and apps installed, ready to use so you can get on with it, really fast. :)
TK over and out..
