and the web browsing is too slow and also download , i tried the connection without the mikrotik its faster , so there is a problem and i think its with the mss 95%. can someone help me how i change them or anything to do . thank you.

Use the change-tcp-mss option.

[admin@111lucia] > /ppp profile print
Flags: * - default  
0 * name="default" local-address=10.0.54.1 use-compression=default use-vj-compression=default use-encryption=default only-one=default change-tcp-mss=yes

[.code]

Also you can change all packets tcp-mss as required.

[…] ip firewall mangle> chain=forward protocol=tcp tcp-flags=syn action=change-mss new-mss=XXXX

Replace the XXXX with your desired mss.
