Tuning up MTU (Maximum Transmission Unit) to speed up Internet access

Now let me tell you one important fact related with tuning. Value of MTU depends upon how fast a connection you have, what kind of activities you perform (ask yourself a question. Are your a mild, average or high end user of Internet ? To put it in other words, Do you download little or nothing, or are an average surfer or are Internet savvy individual and download everything from programs,apps,patches to watching Internet audio/video real-time content?) Depending upon who you are as a user and what kind of connection (modem,dsl,cable or in rare cases T1/T3), this tuning may have little to significant effect on your Internet experience. All right MTU stand for Maximum Transmission Unit.

Value of MTU decides the size of Internet data packet. Bigger the size, more you can transfer.

Analogy could be made with a bucket. If bucket is small, you can carry little but it would be no strain on your strength. Bigger the bucket, more you can carry but it strains your physical strength. (Well! Its not that simple but good enough to understand). Objective should be find a perfect balance which works for you. I think maximum that you can put is as value of MTU is 1500 (but could be higher for your specific network) and it may not make sense making it smaller than 68.Again this is a registry tweak unless and until you have a tweaking utility that can do it for you.Open Registry by going to START-RUN and entering REGEDIT and Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Tcpip\Parameters\Interfaces\ ID for Adapter. For this right click on right pane and add a key by the name MTU. For this key you can add a DWORD value from 68 to 1500 (or higher value is certain cases).If you put less than 68, it will default to 68.

If you put a value higher than 1500 or your Network permitted max, it will default to permitted max.

Enable automatic path MTU size detection and impro

As started on previous tip (Tip 52), MTP size plays an important role in deciding Internet speed. But its not so easy to determine the right value of MTU. For those of us who fall in this category and would prefer computer to find that for us, follow trick may work. I can not say with confidence whether this would work across all network but it should and there is no harm in trying it out. Now before I do that let me tell you what this action will do.

Applying this trick, you would ask computer to automatically find out the maximum MTU size possible in the connection path to a host. This value could be different for different sites. I think this trick should pick the lowest common denominator across a particular path. Typically If MTU size is not optimized, this job has to be done by a router which would mean a significant waste of time (small chunks adds to a considerable loss if you imagine that there are billions of packets involved across the whole Internet) resulting in poor throughout and congestion on cyber lanes. All right this key is called Enable PMTU Discovery.

Again this is a registry.Open Registry by going to START-RUN and entering REGEDIT and Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Tcpip\Parameters\Interfaces\ ID for Adapter. For this right click on right pane and add a key by the name EnablePMTUDiscovery. For this key you can add a DWORD boolean value of 0 or 1 with 1 being TRUE (value that enables auto detection).

Since we are trying this tweak, set to 1 and enable the TCP to attempt to discover the MTU size over the specific path to host.
