Short random test showing perf with tiny amounts of tabs, then opening 300ish tabs, waiting for it to stabilize, and then pulling a tab out to a new window.
I’m admittedly not sure 48gb of ram will be enough, its only been a few days since I got this ram in.
Before this test I had 129 open, brave was using 11,080mb.
You are not trying to run a clickfarm of one machine 
I’m backkkkkkk finally…
I offloaded some old toys / gadgets and felt like splurging. So even if it doesn’t solve the problem (1), it’s a nice rig which should work for a long long time.
Firstly, I opted for a 7950X3D. Which some of you might say is the wrong move.
Here’s my line of thinking:
When the 7950X3D is slower than the 7950X, it’s slower by at most 10% from everything I’ve seen.
When the 7950X3D is faster than the 7950X and other non 3DCache processors, now and then it’s vastly faster, it screams. (So at most, I’m leaving 10% of my performance on the table. Plus I do a lot of ‘weird stuff’ on my systems, I suspect they may be much quicker.)
Finally: I’m using a small ITX case and recycling an old cooler, that cooler is 7950X3D compatible, it’s not compatible with the full 170W regular X.
I’ve got my memory at 6000 with CAS at 32.
(CMK64GX5M2B6400C32) apparently it’ll do 6400, I’m not fussing right now on that, it seems stable.
I’d love to know firstly if these AIDA64 numbers are good or bad?? I know there’s some focus on latency people strive for.

Also these Optane numbers. (I still don’t think it’ll solve the problem but I offloaded a LOT of gadgets, so all in)

Finally a much more dense pic, sorry, any of these numbers look out?
(She’s hitting 75c and slowing herself down a little bit, I’m ok with that as long as she’s quiet)

Any feedback would be great so far. Don’t ask about Chrome yet, just don’t.
(1) Based on early testing, I do not believe it’s going to significantly fix the problem.
I’ve been browsing since an application called NetCaptor:
NetCaptor - Wikipedia
With the right combination of plugins in Chrome, you can replicate most of the NetCaptor functionality.
For me it’s:
Also some stuff which redirects where downloads go (changing folder location) - a tool to close duplicated tabs I’ve opened copies of, as well as some very good ‘search my open tabs’ plugins.
Let me be clear, I do not want this many tabs open, it’s just how I operate, when researching a topic, I can find things very very quickly IF my machine is responsive, but I leave a mess in my wake to get there.
Well I’ve done some googling and it seems I’ve found people with significantly faster memory bandwidth (90,000 highest I’ve seen) and latency as low as the low 50s.
The question is, should I target improving this?
Which optanes? Aren’t they being discontinued?
I grabbed a 905P and a Dell p5800X (only 400GB but that should be more than enough as a non gamer for 5+ years)
The benchmark is with a P5800x using the 905p cable (I believe this cable is incapable of the full speed of the p5800x?)
good to hear
the cables should be the same
I’m at 64GB. I push the system from time to time. I’ve run out of ram several times and if there is no swap I start losing processes to OOM, and it’s not always the RAM gobbler that dies to OOM when you’re out. The dieing process can be an important process with important unsaved state.
You’re probably looking at a software issue, not a CPU/RAM issue. It’s not really designed to scale gracefully for your use case.
Something to try. Browsers will load a copy of each global plugin for each tab. Which means you have x,000 copies of ublock origin running. One for every active tab. Consider dropping ublock in favor of using Brave, which is chromium based that bakes in the ad blocking or just lean into pihole.
Remove any other global plugin or limit the scopes of sites as much as is reasonable. If you use a plugin based password manager, consider swapping to an external password manager. Drop any “nice to have” global plugins. Get the browser as lean as you can. Run zero plugins if you can.
Still may be something fundamental in the design. In which case, if you really want better performance, you really just have to change your workflow somehow.
Wait, what?
I thought Wendel had pointed out the p5800x is capable of PCIE4 (??) and the 905P is only PCIE3.
The cable I’m using, is the one with retail, 905P and Wendel even has a video, desperately going through a plethora of money and cables, trying to gain max speed from a P5800x.
I haven’t done my full benchmarking of the system and stress testing, before she becomes 100% main machine.
HOWEVER.
I agree with your opening sentence. Very approximate brief testing, I seemed to get about double the performance, at best.
Double the performance as in switching from a new tab, back to the one I was on, to the left, took 2 seconds… instead of 4…
I am pretty sure I disabled every single plugin on my system temporarily and it felt faster, for a bit, until it too, turned to crap.
I do need to re-test this but I was fairly sure I did this, to eliminate the variables.
(Does Brave support EVERY plugin Chrome does?)
ah it could well be the case I could be wrong, but they will work
Hey team,
It’s been a long time since I updated.
The 7950X3D is working pretty well, I bookmarked all 5000 tabs eventually into a folder and basically doorstopped them, they may never be clicked again, the 7950X3D just didn’t cut it with 64GB and 5000 tabs, clearly chrome is just not coded to go that far. She’s at 1193 tabs right now and very responsive though.
I’m not convinced the optane ever helped, it was a fun $1000 AUD to spend I guess? At least I know it’ll last a very long time.
Here’s the system in CPU-Z, I think she’s under performing but that’s probably due to my very very very old cooler. (Thank you Noctua for still supporting me)
Here’s CPU-Z
Single thead is only 667 and multi 12566
PassMark 11 CPU shows me quite low on the scale I think?
(54k CPU)
She’s been fairly stable though, I had some onboard GPU (remember, I don’t use a GPU) issues where the driver would crash but that seems to have stopped.
I have had some corruption in some files on my NAS and I need to investigate this quite thoroughly, I can’t recall if those files were written by this machine, so I’ll update if I nail that problem because gollllllllllly if so, ouch. (I’ll clock that ram RIGHT back to 6000 at least)
EDIT: corrupt files due to e1000 bug on proxmox, nothing to do with the AMD rig. This was a painful thing to fix.
Long thread but I was surprised there wasn’t more talk about software settings.
Try setting “processor idle state maximum” to “1” via PowerSettingsExplorer. I also have a 7950x3d and this drops my C6 state residency figure in HWiNFO to zero. This will up idle power usage a bit but seems to improve ‘snappiness’.
Setting windows processor scheduling to “background services” may also help because I’m pretty sure a lot of tabs = a ton of threads and increasing quantum durations may help prevent excess context switching. This setting is buried in the settings app > search for “view advanced system settings” > advanced tab > performance settings > advanced tab (yes again lol).
Setting “interrupt steering mode” to “any unparked processor with time delay” may also help. This is more of a tweak for better mouse tracking while gaming but we are talking about snappiness after all. I’d also disable core parking by setting “Processor performance core parking min cores” to 100%. These settings are also in PowerSettingsExplorer.
Chrome also has a “memory saver” setting that is enabled by default. I disable this because I don’t want chrome to lag when switching tabs but I also rarely open more than maybe 100 tabs and have plenty of free RAM. With thousands of tabs open disabling this may tank performance due to swapping but with swap on an optane it’s not inconceivable that disabling it may still end up being a performance win.
Finally, to see if v-cache helps chrome run all those tabs you’ll need to set the affinity of chrome.exe to only the first 16 threads using process lasso or similar utility, same as you would for a game. Browser benchmarks I’ve run have all shown better performance on the non v-cache CCD but I didn’t have a thousand tabs open.
So I’ve been using thorium for the last month, migrated my chrome profiles over, and it certainly feels significantly snappier. Would be curious what any of you guys notice.
Also been using Speedometer 3.0 to benchmark and relaizing how much certain extensions slow down the browser.
I started changing extension permissions to only run o certain sites.
Have you tried dual booting to linux yet? I am on nearly identical platform as you at least in fedora 40 with amdgpu its night and day difference in regard to latency/snappiness.
Might be worth experiencing just in case. Difference can be felt keenly on 120fps oled monitor. Ha-vent tried front loading firefox with thousands of tabs though, I just have about 1000 around 
Only thing stopping me from moving on full time is god damn lack hdmi2.1 suport to amdgpu drivers due to licensing issues.
I would love to have the knowledge to daily drive linux for my primary machine, however I’m very old with a lot of very very good Windows knowledge.
I have it configured in a very particular way for behaviour and controls, I know how to do things, very very quickly on it, if the machine can keep up.
It seems lately around 2000 tabs is the Chrome “I’m giving up” limit, but Windows itself is generally fairly snappy on the thing.
I have noticed the Alt-Tab handler detests an immense amount of Chrome tabs open too.
Yeah, I’ve got a lifetime of windows experience and all sorts of utilities and setup so it makes switching less attractive, but maaayyybe I try it, esp if it handles multiple screens better.
ps, seriously try thorium.
