https://mvsevm.fsf.net runs a bunch of historical systems on, mostly, a
single RPi 4.
Several years ago I wrote a blog post where I giggled that I was running a
Multics system at much greater than original speed on something that cost
fifty bucks and was the size of a pack of cigarettes. Pretty soon I will
have the time and energy to get my home file/mail/web-server migrated off
its old (2008ish?) Sun x86_64 box, which is big and noisy and sucks a lot
of power onto the 1L PC I bought for the purpose. At that point, finally,
the overhead fan will be the loudest thing in my home office. Also when I
do that the only spinning rust in systems in my house that I leave powered
on (and the number of other ones is shrinking as real SCSI drives give up
the ghost and are replaced by SCSI2SD) will be in my home NAS.

An Old Farts Question, but answers unrestricted :)
In the late 1990’s I inherited a web hosting site running a number of
300Mhz SPARC SUNs.
Probably 32-bit, didn’t notice then :)
Some were multi-CPU’s + asymmetric memory [ non-uniform memory access
(CC-NUMA) ]
We had RAID-5 on a few, probably a hardware controller with Fibre Channel
SCSI disks.
LAN ports 100Mbps, IIRC. Don’t think we had 1Gbps switches.
Can’t recall how much RAM or the size of the RAID-5 volume.
I managed to borrow from SUN a couple of drives for 2-3 months & filled
all the drive bays for ‘busy time'.
With 300MB drives, at most we had a few GB.
Don’t know the cost of the original hardware - high six or seven figures.
A single additional board with extra CPU’s & DRAM for one machine was
A$250k, IIRC.
TB storage & zero ’seek & latency’ with SSD are now cheap and plentiful,
even using “All Flash” Enterprise Storage & SAN’s.
Storage system performance is now 1000x or more, even for cheap M.2 SSD.
Pre-2000, a ‘large’ RAID was GB.
Where did all this new ‘important’ data come from?
Raw CPU speed was once the Prime System Metric, based on an assumption of
‘balanced’ systems.
IO performance and Memory size needed to match the CPU throughput for a
desired workload,
not be the “Rate Limiting Step”, because CPU’s were very expensive and
their capacity couldn’t be ‘wasted’.
I looked at specs/ benchmarks of the latest R-Pi 5 and it might be
~10,000x cheaper than the SUN machines
while maybe 10x faster.
I never knew the webpages/ second my machines provided,
I had to focus on Application throughput & optimising that :-/
I was wondering if anyone on-list has tracked the Cost/ Performance of
systems over the last 25 years.
With Unix / Linux, we really can do “Apples & Apples” comparisons now.
I haven’t done the obvious Internet searches, any comments & pointers
appreciated.
