I've read that Dell offers special version of BIOS for HFT traders for better latency http://www.forbes.com/sites/tomgroenfeldt/2012/12/07/dell-accelerates-servers-for-high-frequency-algo-trading/
It's very interesting:
Moving in and out of turbo mode, however, creates jitter, something that traders want to avoid. Dell’s proprietary technology, which the company plans to patent, turns off seven of the cores and locks the remaining processor into turbo mode running at 3.8 GHz with access to all the cache on the processor.
“We can lock it into that clock speed to minimize jitter and it is fully warranted for three years, can run 24×7 and costs no more than a standard server,” said Bob Barris, vice president of sales at Dell.
Can I somehow achieve the same effect on HP DL360?
