Me? No idea. My last several trading desktops have been dual Xeon server class desktops. Not sure if its due to the ECC or not but desktop or application crashes are virtually non-existant. (Although I am now having some issues with Excel and the RTD links with the new Trading Technolgies platform but thats another story).

For normal multi-threaded apps, obviously more cores is better.

Even though in our case we have hundreds of connections per second, the length of those connections is extremely short and the primary component for us is the single-threaded PHP app that delivers the content. Yes, it pulls from a database (another core via mariadb) and serves it (another core via nginx), but those times are almost zero compared to the time spent in PHP. Each page load for a thread is something like 80% PHP and 20% MySQL.

So throwing a lot of cores at it doesn't improve speed for us, as we are bound to a single threaded app. Our server load is already low most of the time, so we don't need more cores to serve more connections per second. I focus on response time, time to first byte, time it takes for maintenance to complete and various scripts...

During our busy times of day, we see thousands of requests per second, but our response time and TTFB remain largely the same. So while we are CPU-bound, it's a direct result of a single request -> PHP response time, nothing is being "queued up" waiting to execute per se.

You should take a look at AMD Epyc CPU's to replace your Xeon's if you are utilizing multiple cores efficiently. I have been a fan off and on of AMD for a long, long time -- the very first build that I built myself from scratch was an AMD 386/40, and since then they've beat Intel every now and then. This is one of those times, they are handily whooping Intel's butt.

It's funny that AMD was first to release PCIe 4.0 boards this year as well, before Intel...

So now that I revealed we made a hardware change Friday evening, did anyone notice any difference in speed of the site?

This is pure curiosity: I am aware that the "post title" functionality has been removed. Yet, in some instances, it seems some posts are still copying the title from the thread's title.

Example, this was a post from yesterday, where you can see the subtle line that divides the post title from the post:




This is the post's link:




I could not find a way to forcibly re-instate the titles. Is it a glitch or am I missing how to do it?

@xplorer,

I believe this has been fixed, please let me know. Fixed as in corrected so it doesn't appear, to be consistent with everything else.

Mike

I'm pretty sure loading times for threads are faster by several multiples. Could be confirmation bias after reading here, but I doubt it. Plus you will probably have a measure of that to prove it anyways.

Edit: not only threads of course; all pages

That is why I was purposely vague with my downtime message on Friday, I wanted to avoid confirmation bias and delay the announcement a few days.

Yes, I do have metrics that track everything and it shows significant increase in response time.

Thx for the feedback.

Mike

Fixed a problem with the "Can you help answer these questions" section, it was stuck in limbo due to a type-o in my crontab.

It's back to updating again, please forgive the stale/static content for the past few days while this went unnoticed.

Not a huge deal but I did notice in this post that when I click the 200 ticks a month link it goes to one of your old threads instead.



That's on the mobile app btw.

Not checked on the laptop.

Hmm, seems to work fine here on desktop. The 200 ticks link goes here:



That's a 2016 thread. Is that correct?

Just tried on the laptop and it goes to the right place.

It just on the mobile app that it redirects to your old Big Mike's ZN trades post. Weird.
