Performance Difference between machines
I was running some performance tests for the web application I work
MUCH slower on my desktop, even though it's a more powerful machine.
The stats are as follows:
Laptop: Pentium M, 1.86gHz, 1gb RAM, IE7
Desktop: Pentium 4, 2.80gHz, 1gb RAM, IE6
I have confirmed that co-workers with similar setups show the same
others), my laptop returns a time of approximately 50% of my desktop.
Also, if I test performance on a static HTML page, my desktop actually
loads the page faster. So, the page is being returned/rendered faster
on my desktop, but it just seems to be that client side code is
running much slower there.
I have checked and the browser or it's settings don't seem to be the
issue (I tried my desktop with IE7, and I also confirmed that the
settings appear to match)
Also, my laptop has many apps running during these tests while my
desktop doesn't, making me think that the desktop would be faster if
Does anyone know what other settings, configurations, etc could be
causing this?? Any input would be GREATLY appreciated!
The Pentium M and the Pentium 4, while both called Pentium, are in fact completely different architectures. In fact, the newest line-up of Intel CPU's, the Core 2 Duo and Core 2 Solo CPU's, are based on the Pentium M architecture. Overall the Pentium M is more efficient, and in some applications it can even out-perform a desktop CPU.
If you really want to see how the computers stack up, download PCMark05, the basic version is free and it'll measure a number of things, one of which is the CPU. It'll give you separate scores for each componant measured, and also an overall score. Chances are that your desktop will come out ahead.
