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[4]: solaris is meehh

Member since:

The reason it was called Slowlaris was because of its slow TCP/IP stack. It has now been rewritten and is called FireEngine. In older benchmarks I found, Solaris gives 30% more TCP/IP performance than Linux - on same hardware.

Slowlaris was the name given to Solaris x86 in the '90s and it was very slow - if you could get it to install. As for Fire Engine, it was 1/3 faster compared to RHEL 3.0 - that was SEVEN years ago.
Since neither OS has stood still, more recent comparisons of performance and scalability are needed. [/q]
Yes, more recent comparisons are needed. The funny thing is that when I show recent comparisons between Solaris and Linux (Solaris always wins) then I always hear the same argument that say something like

"Come on, your comparison is half a year old! Half a year! Now Linux is on v2.6.43 and not v2.6.39!!! That is not an accurate comparison! More recent comparisons are needed!"

Whereas I have seen comparisons like, Solaris 800 MHz vs a Linux brand new Intel Duo Core at 2.4GHz. And the motiviation is "they have the same price tag, therefore Linux is faster". No, wrong. You should compare the OS on the same hardware. Only then you can draw a conclusion. (And if you compare on the same hardware, Linux looses. Do you want to see links?)
