Adventures with Stahub's Maxonline MOL Ultimate 100Mbit/s FAT GREEN PIPE!

I got my Starhub Maxonline account for 3 months already, which I contracted with them for an entire year with 30Mbit/s down and 1Mbit/s up. I KNEW they were going to increase it to 100Mbit/2Mbit and sure enough, they did.

Only problem was that my existing modem, my old DOCSIS 2 Motorola SBV5120 couldn't give me the 100Mbit/2Mbit. I had to get the DOCSIS 3 Motorola SB6100 modem to achieve that kind of bitrate. But my account was already provisioned for 100mbit, and every day which passed was another day I kicked myself for paying full fare for 1/3 of the performance I was entitled to.

This was a great strategy Starhub had for sucker nerds like me, so I set off to prepare to get the SB6100.

Not an easy task though. The SB6100 did not have VOICE capability, and since I was on Starhub's VOIP Digital Voice service, by itself, the SB6100 can't make it. A quick enquiry told me what I had to do - keep the SBV5120 to use it as VOICE only, and buy a new SB6100 for the Internet bandwidth. Easy enough unless you're a sucker nerd like me - I worried about the signal quality, since keeping the SBV5120 would necessitate another split of the cable, with proportional losses.

This was what I planned:

| (from SCV)
|
|
(splitter1)---------(cable modem)
|
|
(splitter2)----------(VOIP for Digital Voice)
| | | | | |
| | | | | |
(6 way to room outlets for video)

Now I set off to buy a top grade splitter and found the Monster splitter. It cost me S$60. Here it is... a little different from mine, but sufficient to illustrate.



• Ultra low-loss, high-performance video signal splitter for TV & satellite
• 5 MHz - 2 GHz bandwidth is digital ready for splitting DSS & TV signals
• Internal impedance-matched network for accurate 75 ohm load to all outputs
• Precision die-case, 24K gold-plated contacts
• 24K gold-plated contacts ensure high conductive, corrosion-free connections

After doing the change from Regal 2-way splitter to Monster 2-way, this is the result:

Signal strength from the single layer Monster 2-way splitter, increase from 82% to 86% (somebody please tell me, why I split the signal, should half, why still get such high number? Is BS izzit? I don't have meter, so I use my HD set top box to test the signal)

Practical differences:

+Highest DL speed from 30 tries increase from 28Mbit/s to slightly higher than 29 Mbit/s (from utilities.starhub.com)
+Before this, I use 3 way splitter, everytime I press START, I only have a 30% chance of the download proceeding to 100% ... most of the time stuck halfway. After my change to Regal 2 way aplitter, I achieved 100% success, but sometimes need 8 steps of the download bar, sometimes need 6 steps. After change to the Monster, maximum steps is 7 steps, sometimes 6, and very rarely 5 steps. PLEASE NOTE HOWEVER THAT STARHUB INCREASED MY THEORETICAL BANDWIDTH FROM 30MBIT/S TO 32MBIT/S. SO ALL MY RESULTS MAY BE INVALID LIAO.
+Signal quality STAY at 99-100%. No difference between Regal and Monster for Signal Quality. Signal Quality got no difference across all my splits, even the 2nd layer split also SQ is about 99-100%.

Result:
1) Technical wise, not worth S$60. The changes are so marginal.
2) Psychological buff of seeing a nice big gold color splitter, priceless. Achieved.

OK so I went ahead and bought the SB6100, when I got it, I relegated the SBV5120 to a 3rd level split - the phone still worked, so ... fine.

After a very very hard day, where I kick the hell outta myself for stupidity, here are the results for my new SB6100 modem:

speedtest.net figures:


Surprising thing is the incredible upload speed. The Ubicom based router I have detects 3030kbit/s uplink speed, which I thought was wrong, until I saw the speedtest figures. This is the happiest thing, because the downlink speed is something like `too much' at this time, and the great upload speed will help achieve more download speed.

Starhub figures:

All these tests done with the normal idiotic overconservative WinXP settings for RWIN with no frame multiplier. I can achieve more speed - up to 83Mbit/s with Starhub util and 37Mbit/s for speedtest, but with these my upload speed cannot be consistent.

As for why I was stupid, I hardcode a lot of numbers into my ubicom router instead of autodetect, so for half a day, I worked with a hardcoded 30Mbit/s down and 1Mbit/s up figures based on my old connection.

Only after I slept a bit then woke up at about now, I thought of it. Sorry starhub for spamming your mailbox and calling you up so many times. I am an utter idiot loh!

After going to www.dslreports.com and optimizing my RWIN and putting a timestamp on all my TCP/IP packets, this is what I got:

Real world: It took me like less than 5 seconds to download the 50MB Microsoft .NET Framework 3.0: x86 (KB928416) ... LOL!

This was a successful installation, and it was every bit as I expected. But its effect on me is profound, I find myself thinking of all ways on how to use the connection. It's a real change if downloads don't take any time at all relatively.

Anyway, money well spent!

Vista Readyboost - FAT or NTFS, what flash drive to use ...

Vista features a caching technology called Readyboost, where, small files which take the hard disk drive a lot of time to read, are cached in a USB flash drive since USB flash drives have a far faster seek-time compared to Hard disk drives - yes, even Raptors.

There is a lot of talk on Readyboost on the web, but the details are lacking. After googling a bit, here's my take:

1) FAT or FAT32 or NTFS?

Though FAT and FAT32 use less CPU overhead, I thought that FAT would be fastest. Turns out to be not so... I guess it's because today's CPUs are so fast that the CPU overhead is nothing at all. Here're some experimenter data:

Test run #1 (without thumbdrive):

* Average boot time: 1:10m ~ 70s

Test run #2 (FAT32 formatted, 1840MB ReadyBoost swap file):

* Average boot time: 1:13m ~ 73s

Test run #3 (NTFS formatted, 1840MB ReadyBoost swap file):

* Average boot time: 1:05m ~ 65s



2) Format the USB drive at what sector or cluster size?

This is simple. If you have tons of small files, cluster size is an issue, since the smallest files which can be generated and stored is the size of the cluster. So if you have a 4KB cluster size, a 1KB file in fact would still take 4KB. Since Vista uses ONE HUGE FILE, just the default cluster size would be fine. Or any cluster size would be fine. The one detail I haven't worked out is `whether USB drives have a native cluster size'. Anybody can tell me this? I'd be grateful.

3) Which USB flash drive works?

I used the Imation Thumbdrive Micro 1GB, and it worked like a charm.

Discussion thread here, almost everything covered!

Get More Bandwidth by using a better Cable splitter

Thanks to the thread in here: the threadstarter found that his cable splitter was rusty, and changed it with positive results - more bandwidth.

That got a discussion going. And sent me shopping. Here's what I found.

Most cable splitters have these attributes:

• Frequency: the best are 0-1000Mhz, but what I could easily find was 5-1000MHz.
• dB loss: Signal loss for 1-Split-2 and 1-Split-3 is 3dB, but Signal loss for 1-Split-4 is 7dB.
• Isolation: some of the splitters have electromagnetic noise isolation, ranges from 80-120dB, I bought the 120dB one.

There is also a proper connection method: this post details it well:

To achieve a 4 way split, it is advisable to get a 3 way splitter together with a 2 way splitter, rather than to get a 4 way splitter.

4 way splitter will result in at least a 7dB drop in RF signal stregnth to each of the 4 taps. By using a 3 way spliiter, you at least get 2 taps with a 3.5dB drop. My recommendation is to connect your modem to one of the 3.5dB tap, and connect the 2 way splitter to the other 3.5bB tap, together achieveing a 4 way split.

My results? I'm happier with my optimized connection than before. It's little trouble, so doing it gives you peace of mind and at least a psychological boost.
