high spec pix server - improving performance??
« on: 2019 September 29 02:49:17 »
Soo.. I was kindly gifted a new PC (aka server) for my pxinsight processing

its a Dell blade server - specs are dual 2.7 Ghz Xeon processors 24 cores physical  48 core logical - 512GB ram - I have 2 x 250GB SSD's and 2 x 15k spinner in it

bench marks are:

CPU 6600
Swap 1400
Transfer 260 MiB/s

not sure if thats as good as pix can get ?

I have 4 swap files

no ramdrive - alhough benchmark test shows it used a max of 11gb ram!

soo oddles to spare

not sure what else to config or whether it will go faster than this!

??

Cheers

Simon

I suggest you make a large ram drive and use it for all your processing.

It will take a bit of time to copy all your subs and calibration frames to the ram drive before you start your workflow, and it will take even more time to copy the final project file back out for archival, but it will be hugely worth it because I/O will be dramatically faster than with the SSDs.

Not sure that's really covered in the benchmark, but it will certainly speed up your actual work.

yeah the benchmark does not cover that but if you put the swap files on a ramdisk and run the benchmark, you'll get an idea of the speedup possible with airscottdenning's technique.
