BTW
get an immediate 50% drop in CPU by doing:

${fwcmd} pipe 1 config bw 512Kbit/s
${fwcmd} pipe 2 config bw 512Kbit/s
${fwcmd} pipe 3 config bw 256Kbit/s
${fwcmd} pipe 4 config bw 256Kbit/s
${fwcmd} pipe 5 config bw 128Kbit/s
${fwcmd} pipe 6 config bw 128Kbit/s
${fwcmd} pipe 7 config bw 512Kbit/s
${fwcmd} pipe 8 config bw 1024Kbit/s
${fwcmd} pipe 9 config bw 64Kbit/s
${fwcmd} pipe 10 config bw 64Kbit/s

skipto 112 all from any to any out

${fwcmd} add 101 pipe 1 all from any to any MAC any 00:11:22:33:44:55
${fwcmd} add 103 pipe 3 all from any to any MAC any 66:77:88:99:aa:bb
${fwcmd} add 105 pipe 5 all from any to any MAC any 00:01:02:03:04:05
${fwcmd} add 107 pipe 7 all from any to any MAC any 06:07:08:09:0a:0b
${fwcmd} add 109 pipe 9 all from any to any MAC any ab:cd:ef:00:11:22
${fwcmd} add 110 drop all from any to any

${fwcmd} add 112 pipe 2 all from any to any MAC 00:11:22:33:44:55 any
${fwcmd} add 114 pipe 4 all from any to any MAC 66:77:88:99:aa:bb any
${fwcmd} add 116 pipe 6 all from any to any MAC 00:01:02:03:04:05 any
${fwcmd} add 118 pipe 8 all from any to any MAC 06:07:08:09:0a:0b any
${fwcmd} add 120 pipe 10 all from any to any MAC ab:cd:ef:00:11:22 any
