For Solaris 10, with the nmap 4.68 compiled from source, the scan took about 330 seconds (11 times slower than the linux scan!). After it displays the following messages it goes to a complete crawl. Increasing send delay for x.x.x.x from 0 to 5 due to max_successful_tryno increase to 4 Increasing send delay for x.x.x.x from 5 to 10 due to max_successful_tryno increase to 5 Increasing send delay for x.x.x.x from 10 to 20 due to max_successful_tryno increase to 6 Increasing send delay for x.x.x.x from 20 to 40 due to max_successful_tryno increase to 7 Increasing send delay for x.x.x.x from 40 to 80 due to max_successful_tryno increase to 8 Increasing send delay for x.x.x.x from 80 to 160 due to 11 out of 14 dropped probes since last increase. Increasing send delay for x.x.x.x from 160 to 320 due to max_successful_tryno increase to 9 I also find that on Solaris 10 (and Solaris 9) if I run 2 short nmap scans quickly one after another, that the results often change showing me some ports that should be opened or closed as filtered. This results are not consistent, sometimes multiple scans in a row will not show these weird filtered points and sometimes they will not. I have never observed this behaviour on Linux.
Just a guess, can you run the scans on Solaris again with the -d3 option? Somewhere near the end of the output there will be a line like pcap stats: 1717 packets received by filter, 0 dropped by kernel. If the second number is not 0, that points to a packet capture problem. -d3 prints a lot of output so you should redirect it to a file.
