<P DIR=LTR><SPAN LANG="en-us"><FONT COLOR="#2B2B2B" FACE="Arial">When clients are not complaining?<BR>
What I mean is, did you ever seen a client complains about the speed of the Internet connection?</FONT></SPAN><SPAN LANG="en-us"><BR>
<FONT COLOR="#2B2B2B" FACE="Arial">No I do not mean that he or she complains it's too slow but that it's too fast?</FONT></SPAN><SPAN LANG="en-us"></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT COLOR="#2B2B2B" FACE="Arial">I had the pleasure to meet couple clients which complained that the Computer is moving slow</FONT></SPAN><SPAN LANG="en-us"><BR>
<FONT COLOR="#2B2B2B" FACE="Arial">since their Internet connection speed was upgraded. No it wasn't a joke and it is reality.</FONT></SPAN><SPAN LANG="en-us"></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT COLOR="#2B2B2B" FACE="Arial">The scenario needs some background and context to sound a bit more realistic:<BR>
The client is in the age of about 80 and the PC is 2-3 year old. When the Internet connection was slow,</FONT></SPAN><SPAN LANG="en-us"><BR>
<FONT COLOR="#2B2B2B" FACE="Arial">the OS updates and AV P2P connections was slow. Every day the computer got shutdown around a specific hour</FONT></SPAN><SPAN LANG="en-us"><BR>
<FONT COLOR="#2B2B2B" FACE="Arial">and if was required some updates was applied. Now the issue is that since the Internet speed got faster,</FONT></SPAN><SPAN LANG="en-us"><BR>
<FONT COLOR="#2B2B2B" FACE="Arial">every couple hours an update from the AV was applied and almost every couple days an OS update was back on the table.</FONT></SPAN><SPAN LANG="en-us"><BR>
<FONT COLOR="#2B2B2B" FACE="Arial">The main issue was speed but with a twist "when I am disconnecting the router it's working faster" he states.<BR>
Actually it took me quite a while to understand that a simple Desktop with about 4GB RAM should be enough to use:</FONT></SPAN><SPAN LANG="en-us"><BR>
<FONT COLOR="#2B2B2B" FACE="Arial">Skype, Word, Email and couple console based tiny pieces of software.</FONT></SPAN><SPAN LANG="en-us"></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT COLOR="#2B2B2B" FACE="Arial">So why? why did the PC got slower?<BR>
I really do not know! It could be lots of IOPS that was dumped on a 5400 RPMs HDD or that the AV scanned the</FONT></SPAN><SPAN LANG="en-us"><BR>
<FONT COLOR="#2B2B2B" FACE="Arial">2GB of updates repeatedly. I cannot answer what I never understood and from what I understood, faster is not always</FONT></SPAN><SPAN LANG="en-us"><BR>
<FONT COLOR="#2B2B2B" FACE="Arial">the good answer. However I can try to imaging that to verify that every signature of a file is still the same as it should be,</FONT></SPAN><SPAN LANG="en-us"><BR>
<FONT COLOR="#2B2B2B" FACE="Arial">might not be so easy for every PC.</FONT></SPAN><SPAN LANG="en-us"></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT COLOR="#2B2B2B" FACE="Arial">These days I am counting the 10th month which my local testing Squid runs in a "full" http responses digest mode.</FONT></SPAN><SPAN LANG="en-us"><BR>
<FONT COLOR="#2B2B2B" FACE="Arial">Every single response was digested using the SHA256 hashing function and it feels like it's not there at all.</FONT></SPAN><SPAN LANG="en-us"><BR>
<FONT COLOR="#2B2B2B" FACE="Arial">It's not affecting my tiny 15Mbps line rate downloads or my tiny servers farm.<BR>
Ho well it's not the full and the whole truth!!</FONT></SPAN><SPAN LANG="en-us"></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT COLOR="#2B2B2B" FACE="Arial">The full truth is that the users agreed to use the service in any form since they care more about their mind and</FONT></SPAN><SPAN LANG="en-us"><BR>
<FONT COLOR="#2B2B2B" FACE="Arial">soul rather then their comfort. They decided that they need some filtering system when they insert some data into</FONT></SPAN><SPAN LANG="en-us"><BR>
<FONT COLOR="#2B2B2B" FACE="Arial">their mind through their eyes. It's as simple as it sounds. They know that their mind should be guarded under</FONT></SPAN><SPAN LANG="en-us"><BR>
<FONT COLOR="#2B2B2B" FACE="Arial">couple NAT systems and couple IDS+IPS since there are couple weird ideas out there on the Internet.</FONT></SPAN><SPAN LANG="en-us"></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT COLOR="#2B2B2B" FACE="Arial">I am asking myself couple times every single day the questions like:</FONT></SPAN><SPAN LANG="en-us"></SPAN></P>

And my answer is that I do not know what's in there but I can see some "reflection" of something greater and better.</FONT></SPAN><SPAN LANG="en-us"><BR>
<FONT COLOR="#2B2B2B" FACE="Arial">Then I start to wonder, why all these clients wants their so well formed and solid and mature mind to be proxied</FONT></SPAN><SPAN LANG="en-us"><BR>

<FONT COLOR="#2B2B2B" FACE="Arial">there for there is always a need to "spice" the human mind and soul in order to allow it some level of progress.</FONT></SPAN><SPAN LANG="en-us"><BR>
<FONT COLOR="#2B2B2B" FACE="Arial">The most simple example of humans being affected is that kids tries to learn from their parents and later with</FONT></SPAN><SPAN LANG="en-us"><BR>
