Afternoon,
The server is just being rebooted at the moment whilst we up the power. Should only be unavailable for 2 to 3 minutes.
Regards,
Ed

Upping the power and notice are good but you may not yet have had sufficient operations experience (pain from "easy" things going wrong) with regards to the timing. As a technical person, I'm curious about what you're changing and why, though.

Let's hope the problems weren't down to an I/O bottleneck then

Thanks. Seems like web server rather than database server then, since database would more normally want RAM or SSD, though contention can show up as high system (vs user) CPU utilisation and give people the mistaken impression that more CPU power would help.

Let's hope the problems weren't down to an I/O bottleneck then Or in one interesting case I encountered, a CPU overload in a router due to the high number of packets being sent, fixed by adding more CPU power to the router so it could route more packets per second. But Ed and co are unlikely to be anywhere remotely close to that.

Er, what they said, or else I suggest giving it a good thwack on the top (a variation on the tried and tested Engineering principle of "If it doesn't fit, the hammer isn't big enough")

Even with the extra horsepower, performance here was still slow for the first few minutes after 16:00 hrs. I was hoping for several £25 renewal scraps as well as the big one but the refresh rate was getting on for a minute per page.

It was fine for me at 4pm but slightly sluggish at around 3.50pm when I logged in.
I thought the column sorting wasn't working at first as nothing appeared to be happening. It caught up in the end and was ok after that.

Why not run the webserver on GPUs

Generic web servers tend not to be doing the things that GPUs are good with. Generic CPU and RAM are the more likely bottlenecks. RAM based on how much is needed for each connection after allowing for things like reverse proxy usage and CPU depending on how much it takes to do the page building.

There are more cores on a GPU than a CPU. GPUs can be used to increase brute attaching speeds, just think what is could do for MT 4PM issue.

I'm with SteveT on this one. Now, where's that hammer ?
