If I may ask, I post to the list this question (I have no purpose on creating flames/trolls/os wars, just for my personal knowledge).
On the same box (Core 2 Duo, Realtek Gigabit ethernet) I've performed today this simple test, downloading a big file from wu-wien FTP site (it's one of OpenBSD main mirrors). With a clean, partially configured default install of Linux Slackware (kernel 2.6.25) I reached download speeds of about 2.5 MB/s, while the same file from same server (not a round robin server for sure) downloaded on OpenBSD default 4.6 install hardly reached 400 KB/s. I repeated the test again two times, and got the same results. Then I fell over a page (https://calomel.org/network_performance.html) that offers some tweaking to OpenBSD's sysctl, and I dumbly pasted them in my sysctl.conf and rebooted. As (not) expected, download rate in OpenBSD reached almost exactly the same results of Linux Slackware. The main question is why? Do I need to tweak something more to get even better results? Are those settings safe enough to be used? Or the default settings had a strong reason for being there? Why on the FAQ (chapter 6) it says that tweaking net.inet.tcp.recvspace and net.inet.tcp.sendspace won't led to great improvements, while actually I got them? Again, my intentions are *really* positive and I just want to learn more (a quick search on -misc archives didn't led me to much stuff). Thank you Sebastiano
