The demand on memory performance degrades with lower difficulty tests.
I would not trust anything running for short amount of time. EWBF for me died when he cannot even provide a binary over Google Drive (Trojan detection.)
DTSM became the miner of my choice thanks to a benchmark posted on http://www.zcashbenchmarks.info/

I still stand with my first assessment that the main downfall of this client is the ability to communicate and state things clearly...
 - Difficulty is not a float, but hex
 - Log is just an extension of the command line output
 - Command line output is just a status message
 - Telemetry replaces command line output (Good thing)
 - Current log makes little sense without further tools. (I would appreciate more details)

I think the log should contain:
 - TCP communication details (Hostname, IP, Port)
 - Share details (More than just + or *)
 - no performance ticks (Could be replaced by TXT file for benchmarking.)

Anyway I am looking forward to new versions, but I am sticking with 0.5.7. Performance on 0.5.8 is worse for me CPU wise.
