Google Chrome Cancels Paused Downloads

Monday, September 22nd, 2008

I’ve been running Google Chrome on both XP and Vista PCs since it became available. I discovered an annoying shortcoming about it a few minutes ago. I started downloading the Linpus Linux Lite Live CD ISO using Chrome. Since the estimated download time is around 15 hours, I decided to pause it and exit Chrome. Firefox allows you to resume a download between sessions. Unfortunately, Chrome does not. Fortunately, I tested this before powering down my Vista PC. So, I fired up Firefox 3, started the download, and paused it. I also tested closing the browser, restarting the browser, and resuming the download. This all worked fine.

The lesson learned here is to start any large file download using Firefox. It lets you pause and resume between separate sessions. Google Chrome does NOT.

Aero Glass Too Much for a Quad-Core w/4GB RAM: Turned Off Aero Glass

Thursday, September 18th, 2008

My old eMachines T6420 Athlon 3200+ machine running Vista died last month. So, I bought a Dell Inspiron 530 desktop running Vista to replace it. The old machine had a single core AMD chip and 2GB RAM. The new one has a quad-core Intel chip and 4GB RAM. Guess what? It feels like the new quad-core runs slower than the old single-core. Some apps like Corel PaintShop Pro XI are barely useable and often crashes (both PCs run the 32-bit version of Vista, btw). I had planned to switch from my still functional main PC running XP to this Dell running Vista. But, XP on the old PC runs so much faster, I’m having second (and third) thoughts. One thing that really help speed up the Dell and reduce disk thrashing was to turn off all of the Aero and Aero Glass features in Vista Home Premium Edition. You can see the few options I left turned on in the screencap above.

Anti-Virus Slows Down File Copying

Saturday, September 13th, 2008

Copying files on Windows XP PC is incredibly slow compared to the same operation on a Linux or Mac OS X computer. And, don’t get me started on Vista. I just bought a quad-processor box running Vista and it is slower in pretty much everything than my four year old AMD Athlon box running Windows XP.

There are probably a lot of factors involved including file handling routines, the directory management, and general code inefficiency. But, over the years I’ve added another factor: Microsoft Windows’s numerous and multiplying security issues. The real-time anti-virus and anti-spyware software we have to run to help deal with this problem has what looks like a big impact on copying files. This is especially noticeable when a lot of files are being copied.

Here’s an example: The PC I had running Vista died a few weeks ago. So, I bought a disappointingly slow quad-processor replacement (no fault of the Dell hardware, btw. The slowness is all Vista’s fault). Now, I’m taking the two hard drives from the dead PC (system board issue) and redistributing them to other desktops. I’m moving files from an old 120GB HD in my current main PC running Windows XP to a 160GB drive that came out the dead Vista box. Both are D drives (second drives). So, it is just a matter of moving data files. Copying the files from one drive to the other is taking forever because of a number of annoying factors. One is that Windows file copying is just slow. Another is that Windows stops for annoying reasons like asking if I want to copy a read-only file. Of course, I do? Why not? And, then, of course, there’s the anti-virus software doing its job by checking every file as it is copied. I’ve seen it spike to over 90% processor use during this copy process. And,it tends hover between 35 and 75% of processor use most of the time.

So, the PC is nearly unusable during a simple file copy and the file copy process itself takes an extended time because of security checks. So, the end result is hours of unproductive PC hours and draining electricity too.

Addendum: I should add that the Avast free anti-virus edition I’m using is one of the lighter weight and more efficient anti-virus solutions I’ve tried. Other anti-virus solutions noticeably slowed down my PC 100% of the time, not just during file copying.

HP Ink Use & Cost Mystery

Thursday, September 11th, 2008


The use and cost of inkjet ink never ceases to amaze me. I’m glad the the HP Photosmart C6250 (which has given me a lot of problems to solve) uses individual color cartridges. I really don’t understand how each color is used by my specific usage pattern. But, I am surprised that it looks like it is cheaper to buy indivdual HP 02 cartridges rather than the entire color pack (black ink is no longer included in that pack). I think someone estimated that inkjet cartridges costs something like $8,000 per gallon. So, I wish I could get a better handle on how it is actually used in my printer (given the kinds of things I print).
