Hi Mr Amos ,
thanks very much for explanation .
thanks Marcus ,
so ,
you mentioned that i have to fix the ... and // in squidguard !! how could
i fix it ??!!!!!!
i want to say something !
ive removed squid 1.4 and installed squidguard 1.5 beta version .
after that ,
no bypass happened :)
i mean that it was seem to be problem of squidguard .
i read that there is a bugs in squidguard in bypass , and i found squid 1.5
is better .
i pumped 2000 users to squid with BW 200M and no by pass occured
this is one issue ,
now lets return to the issue of slow browsing ,
agian , the browsing is not very bad , but it is acceptable anyway and less
quality than in absense of squid .
i dont know if it was because of my hardsiks !!
my disks are as bellow :
hd1==>ssd with 180 G as operating system
hd2==>sata with 560 G as /cache1 storage
hd3==>sata with 560 G as /cache2 storage
hd4===>sata with 560 G as /cache3 storage
now i dont know if i need more hardiks additional to hd2, hd3 , hd4 ?
or i need to replace them by ssd ?
or i need to use another file system to enhacne the speed ?
You may advice me Mr Amos about the best choice :)
===========================
now , after all of modification i did,
i mean after i used squidguard 1.5 beta , i will post my logs of squidguard
and cache..log
note that im still using squid 3.1.0 , i downloaded it by yum install !
============================
