Search speed will increase or not if you use:
- HDD, SSD, M.2 or DDR vertual disk?
-32 cores or 64 processor cores?
HDD speed doesn't matters.
If you using CPU then more cores => more threads => more speed.
We are talking about multithreading or we need to run 64 commands?
For example, Brainflayer works only on one core.
There is no need to run 64 different instances of Kangaroo at once, use the -t <number of threads> option to launch that many worker threads.
I wouldn't run Kangaroo on a virtual disk because of the overhead of running programs inside a VM, but other than that, since Kangaroo isn't a disk intensive program it doesn't matter which disk you run it on.
I ordered a computer with AMD Ryzen Threadripper PRO 3995WX 4.2 GHz and 256 GB of RAM. The motherboard ASUS Pro WS WRX80E-SAGE SE WIFI has 6 x PCI 16. I have not decided on the video cards yet.
