I'm a liitle stunned. Happy, but stunned.

In the past, I'd get approx. 5-6Mbps broadband speed in Hamilton, NZ.
But I did NOT do a speed test just proir to my Linksys E4200 upgrade, so I'm relying on those from a few weeks ago.

I upgraded the firmware of my Linksys E4200 to Tomato firmware.

Now, in Hamilton NZ I'm getting a consistent ~10Mbps bandwidth rate.

Like I can not believe a change of firmware on a router is going to double LAN/WAN uplink speed.

I know (and believe me I know) you can stuff up routing/switching, but my config is the same as the original Linksys firmware, with the same Ethernet setting and static gateway IP. (no spanning-tree or routing)

My ADSL2+ modem is a TG585-V8

It appears to me that my ADSL2+ line is capped at 10Mbps. (ADSL2+ being approx 24Mbps)

I've run a few speed tests and all return a bandwidth speed of 9999Kbps or slightly lower.
I have never seen anything above 10Mbps.

Is 10Mbps normal? (like I'm thinking it's preety good)

Whatever the outcome, I'm quite happy with the current bandwidth rate. ... unless or course, someone else has better throughput.

It is possible you've just been recently cabinetised?

Average stats for a cabinetised customer are speeds of around 13-14Mbps with a maximum of 18Mbps due to the noise margin Telecom use so technically you are slight below average. Without seeing your line and sync stats it's not really possible to provide any other feedback or comments on the performance of your connection.

I "fixed" a friends internet the other day, changed some settings and his "max connect" (may differ from "actual connect") speed jumped from 7Mbps to the full 20Mbps, a test download was sitting on 1.8MB/sec. Pretty sure I can look out his window and see a cabinet though.

My connection at home isn't far off, connect speed of around 15Mbps, transfer throughput is consistantly >1MB/sec.

I did some work on a friends ADSL connection a few weeks back and speed went from 500k DL to over 10 Mbps,

Steve Biddle also helped which was very good of him,

Ah so, I wasn't having a senior moment then. It is real.
So it's a bit like, wait, there's more.

My line is a bit on the dodge side. Had a second Telecom line previously which was much cleaner than the primary house wiring. Plan to reconnect the second line via a VDSL2 filter/splitter and handoff the DSL to one wall outlet.

Line errors follow, where any CRC errors are bad errors.

Hi, 13Mb/s sync rate for 21dB attenuation seems a little light I would expect closer to 15, but without a clean line with a master filter you cannot expect to acheive max speeds.
