High Network Buffering and TCP Optimizer settings

Ok, it's not long since i had a terrible "hiccup" in my net speed. I don't know why, but it happened.
So i ran an analysis test from http://netalyzr.icsi.berkeley.edu/index.html
and it seems i suffer by a very high network buffer. So i searched the forum and i saw that another guy had a similar(?) problem with
me and you helped him change his TCP Optimizer settings/values. Can you the same with me? I can provide you with whatever info
you need for that.

Thanks in advance.

It is typical for the netalyzr results to state "high network buffer" for high-speed / high-latency lines, like most broadband internet connections. You can always set your TCP Windows auto-tuning level from "normal" to "restricted", however, your speed/throughput will suffer.

What kind of "hiccup" did you have ? It's most likely due to something else with your connection, rather than the buffering.

that "hiccup" was a very unstable speed. it all started, god knows when, and my ping in different games hops like there's no tomorrow.
e.g.: Aion EU: normal ping for me (i live in greece) 90 ms. after "that" day: 122 - 130 - 90 - 80 - 230 etc..
League of Legends: normal ping 70 after "that" day: 230 - 450 - 100 - 90 - 70 etc..

yeah, i know, that ping depends on the server status, server population and many more, but these hops are just absurd! a normal hop would be +20ms or -20ms or something...

What you should look at is the first hop that those variations occur - if it is close to you (within the first 3-4 hops), it may be your ISP, some node getting congested.

We also have some tweaks that can help stabilize latency you may want to check out here: http://www.speedguide.net/articles/gaming-tweaks-5812

i tried those gaming tweaks TCP Optimizer and Leatrix Latency Fix didn't do by themselves and i noticed a very small difference in my ping (10ms lower).
now idk what else to do....

Do a tracert when you're experiencing problems, and note where the ping spikes are FIRST occurring, i.e. is it the first hop (your router), first few hops (your ISP), etc. That will give you an idea where the culprit is, at least.
