There are some good windows web proxies about. The only problem with them is they sometimes dont natively act as a transparent proxy. i.e. typically you’ll need to set your client machines to a specific IP and port.
I’ve used squid historically when setting up transparent proxies (mainly since it actually has a transparent mode) and this has worked well. Recently i thought i’d have a go at some of the windows solutions to see how they pan out.
netsh is going to be the tool to assist in this case. Here is a typical use for netsh;
>add v4tov4 listenport=80 connectaddress=127.0.0.1 connectport=8080
This should grab all traffic that hits your machine bound for port 80 and redirect to port 8080.
You’ll also need to make sure that routing is enabled, so your machine can act as a gateway between the requests and the real outbound gateway (typically your dsl modem)
Want to move your current disk image onto a SSD drive?
Quick, easy and free. Also aligns disk sectors :)
Quick way to check that TRIM has also been enabled;
fsutil behavior query DisableDeleteNotify
If the result is ‘0’ TRIM is enabled.

I’ve run through this exercise again – my old findings here
4 x 500 WD Black drives — in one big RAID 0 (128K blocks)
and again only using 500GB of capacity (roughly 1/4 of each of the drives)
get folder 2 ISO – portable app that does what is says. No limits just works. http://www.trustfm.net/divx/SoftwareFolder2Iso.php
This command will confirm if TRIM has been auto-enabled by windows 7
fsutil behavior query disabledeletenotify
DisableDeleteNotify = 1 (Windows TRIM commands are disabled)
DisableDeleteNotify = 0 (Windows TRIM commands are enabled)
If you would like to force it on;
fsutil behavior set disabledeletenotify 0
You must create your ODBC connection using the 32-bit ODBC program. It is not as simple as running odbcad32.exe from the run / search bar.
you must run the following to get the actual 32-bit version;
Populate this with the details and you should see it in the virtual center installer.
I’ve run into some issues lately with XP guests that are running off a IDE controller. If you want any kind of performance you must build your machine with the LSI drivers (parallel).
Here is a flp image with the required LSI drivers (Press F6 etc on xp boot)
I’ve got some old 250Gb drives that are starting to show their age. I’ve currently got them setup in a 3x RAID 0 config which presents about 750Gb of space.
I’ve got everything on a single partition (meh, i’m lazy). I’ve done various speed tests in the current setup (with all space allocated), but i thought i’d re-image onto a short stroke partition.
I only use about 150Gb of space on my main machine (most of my data is on another box), so i’m going to try creating a 200Gb partition to test if this provides any kind of performance boost.
So reducing my raid 0 from 750Gb to 214Gb, and here are the results…
Before with all 750Gb presented…
Same disks but short stroked to 214Gb….
Conclusion : Yip, seems like its worth it if you have the spare space. Average throughput is up by 10MB/s and seek has improved by almost a third loosing 4ms.
You will get even more of an improvement if you can use a smaller % of capacity per drive and / or more drives for your stripe.

btw – the above was without write-back cache enabled…. if i turned that on i got the following…
