Topic: Sme (Squid) + Satellite Link

[volipind]

I m using a bi-satellite link with a gilat satellite router and few pc's of my lan; i want increse the surf speed then installed sme+squid,but the user navigation is slow than the past;
without sme,in the browser option i specify use proxy aaa.bbb.ccc.ddd port 9877 (the ip adress of gilat router).
whith sme running if i specify in the browser tab the adress xxx.yyy.jjj.kkk 3128 (the ip of my sme) the speed navigation is very slow,i can correct this only specyfing aaa.bbb.ccc.ddd port 9877,but in this way the cache won't be used/updated;here's my squid conf:
