Linux When it comes to the fast-moving business of trading stocks, bonds and derivatives, the world's financial exchanges are finding an ally in Linux. As late as 2007, Wall Street exchanges were still largely run on Unix . . . Over the past few years however, Linux has crept into this market, showing up first in ancillary systems and then running a few core exchanges.

RE[3]: solaris is meehh

A decade ago, our company was selling software solutions on both solaris and linux. It was very IO / CPU hungry. After seeing 2x >$100k sun boxes handily beaten by single x86 linux machine costing around 15k only ~1.5 years later, it was quite clear sun was on a steep downhill. We really couldn't find anything compelling about sun machines or solaris. Most praises about it seem pretty nostalgic to me.

Yeah, I heard something similar. One large company switched from Solaris SPARC to Linux and got much higher performance.

Because I know from several official benchmarks, that Solaris gives much higher performance than Linux - on the same hardware (SAP benchmarks, I/O, TCP/IP, etc) I dug further into this. And I found out that...

The company switched from 800 old SPARC servers at 1GHz, to 4.000 brand new Intel duo core at 2.4GHz running Linux. I would be very surprised if they did not see a performance increase?

In your case, the old Solaris servers, did they run at 1GHz, and you switched to Linux octo core cpu servers running at 3GHz?

You know, several benchmarks shows that running on the same hardware - Solaris gives much better performance. Is you installed Solaris on your hardware, you would get an additional boost in performance. You want to see links?
