I've find out a very simple way to Qos my network config, I've only a very slow (700k download) bandwidth and only 400 Mhz Router cpu, but it works very well, I can open 6 YouTube Videos on Mozilla and Simultany navegate my Facebook or each other Site on Chrome !!!
My settings are based on the digital basis, 0 + 1 + 0 + 1 + 1 + 1, yes or no, cold or hot, good or bad, prioritized or no prioritized, very simple but effective !!

1. Step, run this to create schedule rule, to edit any go to schedule and edit

/system scheduler
add comment="Dns to Fw and Queue Tree" interval=1m name=\
"Dns to Fw and Queue Tree" on-event="## Dns to Fw and Queue Tree ##\r\
\n## Testet under RouterOS 6.38rc8 ##\r\
\n## Written by BrasDeutscher,PA,Brazil ##\r\
\n{\r\
\n## Set the list name here ##\r\
\n:global ln \"Limited\"\r\
\n\r\
\n## Set the list timeout here ##\r\
\n:global ttl \"1h\"\r\
\n\r\
\n/ip firewall address-list remove [find where address=0.0.0.0 ];\r\
\n/ip firewall address-list remove [find where ! dynamic list=\"\$ln\" ];\
\r\
\n\r\
\n## Set the content here ##\r\
\n:global cont1 \"video\"\r\
\n:foreach d1 in=[/ip dns cache find where (name~\"\$cont1\") type=A ] do=\
{\r\
\n:if ([:len [/ip dns cache get \$d1 address ]] < 16 ) do={\r\
\n:local ip1 [/ip dns cache get \$d1 address ];\r\
\n:local dnsn1 [/ip dns cache get \$d1 name ];\r\
\n:if ([/ip firewall address-list find where address=\$ip1 ] = \"\" ) do={\
\r\
\n/ip firewall address-list add list=\"\$ln\" address=\$ip1 timeout=\"\$tt\
l\" comment=\"\$dnsn1\";\r\
\n}}\r\
\n}}" policy=ftp,reboot,read,write,policy,test,password,sniff,sensitive \
start-time=startup

2. Step setup Layer7

/ip firewall layer7-protocol
add comment=EXE name=EXE regexp="\\.(exe)"
add comment=RAR name=RAR regexp="\\.(rar)"
add comment=ZIP name=ZIP regexp="\\.(zip)"
add comment=7z name=7z regexp="\\.(7z)"
add comment=CAB name=CAB regexp="\\.(cab)"
add comment=ASF name=ASF regexp="\\.(asf)"
add comment=MOV name=MOV regexp="\\.(mov)"
add comment=WMV name=WMV regexp="\\.(wmv)"
add comment=MPG name=MPG regexp="\\.(mpg)"
add comment=MKV name=MKV regexp="\\.(mkv)"
add comment=AVI name=AVI regexp="\\.(avi)"
add comment=FLV name=FLV regexp="\\.(flv)"
add comment=WAV name=WAV regexp="\\.(wav)"
add comment=RM name=RM regexp="\\.(rm)"
add comment=M4A name=M4A regexp="\\.(m4a)"
add comment=MP3 name=MP3 regexp="\\.(mp3)"
add comment=MP4 name=MP4 regexp="\\.(mp4)"
add comment=RAM name=RAM regexp="\\.(ram)"
add comment=RMVB name=RMVB regexp="\\.(rmvb)"
add comment=DAT name=DAT regexp="\\.(dat)"
add comment=DAA name=DAA regexp="\\.(daa)"
add comment=ISO name=ISO regexp="\\.(iso)"
add comment=NRG name=NRG regexp="\\.(nrg)"
add comment=BIN name=BIN regexp="\\.(bin)"
add comment=VCD name=VCD regexp="\\.(vcd)"
add comment=WMA name=WMA regexp="\\.(wma)"
add comment=JPG name=JPG regexp="\\.(jpg)"
add comment=JPEG name=JPEG regexp="\\.(jpeg)"
add comment=PNG name=PNG regexp="\\.(png)"
add comment=GIF name=GIF regexp="\\.(gif)"
add comment=WEBM name=WEBM regexp="\\.(webm)"
add comment=3GP name=3GP regexp="\\.(3gp)"
add comment=3G2 name=3G2 regexp="\\.(3g2)"
add comment=MPEG name=MPEG regexp="\\.(f4v)"
add comment=F4A name=F4A regexp="\\.(f4a)"
add comment=F4B name=F4B regexp="\\.(f4b)"
add comment=F4P name=F4P regexp="\\.(f4p)"


3. Step add adicional firewall filter rules
# Set your Wan interface name here #
:global int "Wan-interface-name
/ip firewall filter
add action=jump chain=forward comment=Qos jump-target=Qos layer7-protocol=3G2
add action=jump chain=forward comment=Qos jump-target=Qos layer7-protocol=EXE
add action=jump chain=forward comment=Qos jump-target=Qos layer7-protocol=3GP
add action=jump chain=forward comment=Qos jump-target=Qos layer7-protocol=F4A
add action=jump chain=forward comment=Qos jump-target=Qos layer7-protocol=F4B
add action=jump chain=forward comment=Qos jump-target=Qos layer7-protocol=F4P
add action=jump chain=forward comment=Qos jump-target=Qos layer7-protocol=\
MPEG
add action=jump chain=forward comment=Qos jump-target=Qos layer7-protocol=7z
add action=jump chain=forward comment=Qos jump-target=Qos layer7-protocol=BIN
add action=jump chain=forward comment=Qos jump-target=Qos layer7-protocol=FLV
add action=jump chain=forward comment=Qos jump-target=Qos layer7-protocol=ISO
add action=jump chain=forward comment=Qos jump-target=Qos layer7-protocol=M4A
add action=jump chain=forward comment=Qos jump-target=Qos layer7-protocol=MKV
add action=jump chain=forward comment=Qos jump-target=Qos layer7-protocol=MOV
add action=jump chain=forward comment=Qos jump-target=Qos layer7-protocol=MP3
add action=jump chain=forward comment=Qos jump-target=Qos layer7-protocol=MP4
add action=jump chain=forward comment=Qos jump-target=Qos layer7-protocol=RAR
add action=jump chain=forward comment=Qos jump-target=Qos layer7-protocol=WAV
add action=jump chain=forward comment=Qos jump-target=Qos layer7-protocol=\
WEBM
add action=jump chain=forward comment=Qos jump-target=Qos layer7-protocol=WMA
add action=jump chain=forward comment=Qos jump-target=Qos layer7-protocol=WMV
add action=jump chain=forward comment=Qos jump-target=Qos layer7-protocol=ZIP
add action=jump chain=forward comment=Qos content=download jump-target=Qos
add action=add-src-to-address-list address-list=Limited address-list-timeout=\
1h chain=Qos comment=Qos connection-bytes=10000000-0 connection-rate=\
128k-20M in-interface="$int" protocol=tcp
add action=add-src-to-address-list address-list=Limited address-list-timeout=\
1h chain=Qos comment=Qos connection-bytes=10000000-0 connection-rate=\
128k-20M in-interface="$int" protocol=udp

4. Step add firewall mangle rules, edit your interface-names
# Set your Lan interface name here #
:global int1 "Lan-interface-name"
/ip firewall mangle
add action=mark-packet chain=prerouting comment=Upload in-interface="$int1" \
new-packet-mark=Upload passthrough=no
add action=mark-packet chain=postrouting comment=Limited new-packet-mark=\
Limited out-interface="$int1" passthrough=no src-address-list=Limited
add action=mark-packet chain=postrouting comment=Unlimited new-packet-mark=\
Unlimited out-interface="$int1" passthrough=no src-address-list=!Limited

5. Step add new queue types, you must ajust the pcq dst and src-address-mask to your own network size

/queue type
add kind=pcq name=Limited pcq-burst-rate=768k pcq-burst-threshold=512k \
pcq-classifier=dst-address pcq-dst-address-mask=29 pcq-rate=256k \
pcq-src-address-mask=21
add kind=pcq name=Upload pcq-burst-rate=512k pcq-burst-threshold=384k \
pcq-classifier=src-address pcq-dst-address-mask=29 pcq-rate=256k \
pcq-src-address-mask=21
add kind=pcq name=Unlimited pcq-burst-rate=1M pcq-burst-threshold=768k \
pcq-classifier=dst-address pcq-dst-address-mask=29 pcq-rate=512k \
pcq-src-address-mask=21

6. Step add queue-tree rules

/queue tree
add comment=Upload name=Upload packet-mark=Upload parent=global queue=Upload
add comment=Limited name=Limited packet-mark=Limited parent=global queue=\
Limited
add comment=Unlimited name=Unlimited packet-mark=Unlimited parent=global \
priority=2 queue=Unlimited

7. Step, if you need diferent bandwidth for night and day run this in new terminal

/system scheduler
add comment="Daytime - 1" interval=1d name="Daytime - 1" on-event="## Daytim\
e ##\r\
\n{\r\
\n:global ref \"512k\"\r\
\n:global pref [:pick \$ref 0 3 ];\r\
