 |
|
I've set up an UltraSPARC 5 with netBSD as my router, but I'm currently having some performance issues.
I'm on a 100MBit full-duplex connection.
My friend has a server located in our school and when I download from it I max out at ~4MB/s. But when he downloads from it (to his computer at home) he max out at ~9.5MB/s.
I've noticed that the computer spends most it's time waiting for something (top reported ~80% interrupt time when downloading), changing ipfilter's log policy from everything to blocks reduced that to ~70%, but I'm still capped at ~4MB/s.
This is when I download to the router, when downloading to a machine behind the router I'm capped at ~3.5MB/s.
The reason that I've described all this is that I'm hoping that someone will know what's wrong 
But the real reson for this thread is that I wan't to know if installing Gentoo on that machine is likely to increase performance.
I've also heard some rumors about ipfilter/ipnat running on Linux, does anyone know of this? Two reasons to stay with *BSD (or switch to Solaris) are those, iptables is a pain in the *ss compared to ipfilter/ipnat.
I've tried both OpenBSD and netBSD - netBSD performing a tad better. I've been thinking about trying Solaris on it, but my friend discouraged me saying that it was hard making it secure enough when you haven't worked with Solaris before.
Here's the device info from netBSD's dmesg:
| Code: | mainbus0 (root): SUNW,Ultra-5_10: hostid 80a22042
