Bee to the blossom, moth to the flame; Each to his passion; what's in a name?

I like the sentiment of Helen Hunt Jackson in that quote and it generally applies double for computer system names. However I like to think when I named the first NetSurf VM host server phoenix fourteen years ago I captured the nature of its continuous cycle of replacement.

We have been very fortunate to receive a donated server to replace the previous every few years and the very generous folks at Collabora continue to provide hosting for it.

Recently I replaced the server for the third time. We once again were given a replacement by Huw Jones in the form of a SuperServer 6017R-TDAF system with dual Intel Xeon Ivy Bridge E5-2680v2 processors. There were even rack rails!

The project bought some NVMe drives and an adaptor cards and I attempted to arrange to swap out the server in January.

Here we come to the slight disadvantage of an informal arrangement where access to the system depends upon a busy third party. Unfortunately it took until May to arrange access (I must thank Vivek again for coming in on a Saturday to do this)

In the intervening time, once I realised access was going to become increasingly difficult, I decided to obtain as good a system as I could manage to reduce requirements for future access. 

I turned to eBay and acquired a slightly more modern SuperServer with dual Intel Xeon Haswell E5-2680v3 processors which required purchase of 64G of new memory (Haswell is a DDR4 platform). 

I had wanted to use Broadwell processors but this exceeded my budget and would only be a 10% performance uplift (The chassis, motherboard and memory cost £180 and another £50 for processors was just too much, maybe next time)

While making the decision on the processor selection I made a quick chart of previous processing capabilities (based on a passmark comparison) of phoenix servers and was startled to discover I needed a logarithmic vertical axis. Multi core performance of processors has improved at a startling rate in the last decade.

When the original replacement was donated I checked where the performance was limited and noticed it was mainly in disc access which is what prompted the upgrade to NVMe (2 gigabytes a second peek read throughput) which moved the bottleneck to the processors where, even with the upgrades, it remains.

I do not really know if there is a conclusion here beyond noting NetSurf is very fortunate as a project to have some generous benefactors both for donating hardware and hosting for which I know all the developers are grateful.

Now I just need to go and migrate a huge bunch of virtual machines and associated sysadmin to make use of these generous donations.
