The Solaris machines go MUCH slower than the Linux machines. Note the the below issues only appear to occur with Syn and UDP scans. They do not appear to affect connect scans.
This sounds like a pcap buffering issue. Do your versions of solaris use BPF or DLPI or ...? If BPF, it could be that putting the pcap descriptor into BIOCIMMEDIATE mode would help: http://seclists.org/nmap-dev/2007/q1/0174.html If you could apply this patch http://seclists.org/nmap-dev/2007/q1/att-0174/nmap-4_21ALPHA1-openbsd-performance_patch removing the #ifdef OPENBSD and possibly changing the constant to whatever is found in your /usr/include/net/bpf.h and then test the performance, this would be a big help. One of the reasons why this patch wasn't applied is that we weren't sure which systems it should be used on. Ideally tcpip.cc would #include <net/bpf.h> but I had problems with redefining BPF structures when I tried this, hence the hard-coded constant. Doug
