New design is CPU intensive to render....

Last.fm has always been hungry. I know people who don't use the site because it slows everthing else down.

: (

There are some known performance issues (particularly in IE6) that we're working on, but in most browser and on relatively old machines we've not had too many problems.

If you could let us know which browser/operating system you're using then it will help us in trying to speed things up :)

personally i dont need flashy graphics, i would rather have my cold hard statistics in CSV format. But as they are sexed up, i'm glad that it is done in elegant style.

Firefox and Safari on an intel core 2 duo 2.16 GHz macbook with 4GB of ram has cpu usage move between 10-25% while sitting on the profile page, at least on my set up. No clue what it use to be. I haven't noticed any major slow downs on my set up personally. I don't know what "allowable" cycles for a webpage are, but that's what it is.

I'd say there is no doubt that the page is pulling some cycles, especially since if I have either browser on just a forums page the cycles drop well below 10%.

So yup, looks like the staff could do with some statistics from anyone having apparent issues so they can look into it and optimize it.

I'm surprised people get it that high with a decent system.

I use firefox on Vista-64bit, intel 2.4Ghz quadcore with 4GB RAM and 1 core is 2-4% and the other 3 are barely registering when viewing the profile. And that's with WMP and MusicIP at idle in the background. There's obviously some optimization depending on the system OS and browser.

Since not all programs use multi cores in a good way, that may have something to do with it as well. Who knows how it is from OS to OS.

Though even though the cycles seem high, I don't feel like my performance is lacking in the face of it.

Hey guys,

No need to be mean :P

With the new site there are still some instances were a modern system will struggle. We've had a few instances where the flash player or some errant javascript has hogged the CPU.

Every report of this can help us find and eliminate the problems :)

Browser? with his old CPU disinclined laptop, he won't know what that is.

And the OS will probably be Windows3.1, and you should work on this assumption untill he bothers to reply.

To be clear, I'm not complaining about the laptop. I'm just using it as an example to point out how drastic the difference in load is for me between the new and old versions. I've edited my original post to make that clear. I'm experiencing problems on the desktop

Operating System is Debian Linux 4.0, Browser is Iceweasel 2.0.0.15 (basically, rebranded firefox). I have 768Mb memory (I know that's not a lot), and CPU is an Athlon 64 X2 4000+

Could lack of memory be an issue? I don't see why it should be, but that's the biggest bottleneck on this box.

Incidentally, the laptop is also running debian 4 (in a stripped down configuration) with iceweasel, and has a pentium II (not sure what clockspeed) and 128MB RAM. And no, I don't expect to get things working on that. :)

It is that Flash player of yours.

No idea why you have such bad performance on the site... or why anyone does for that matter.

My PC has been sitting here just over 3 days on this restart, and with all these apps open, and maximized, not minimized. WMP is playing video, iTunes is playing music and I've made sure they all use some ram at least. This is the performance I am getting:





Here are my system specs.

I'm using Firefox 2.0.0.16 on Windows XP.

I noticed that the memory footprint of Firefox gradually gets bigger the longer I browse last.fm:



When things start to slow down, I just restart Firefox and it's back to normal, but this didn't happen before so maybe there's a clue here.

For the record, I really don't consider what I'm gettign "Bad performance" It's not causing me any issues. I'm just letting people now the load. It's not like it's causing me bad browsing, etc. It just does take up some cycles, for what I do on my computer it's absolutely no issue at all it doesn't slow me down any. It's just what it is, and I have no idea why it's different from others with similar systems either, but it's not causing any true performance issues.

I did a little checking myself, and went to my profile page with Task Manager open. CPU usage shot up to near 50%, with Firefox using 45%. My computer usually idles at about 2-5% CPU usage. I'm running Windows XP on a 3.2 Ghz Pentium IV with 2.5 GB of RAM, and Firefox 3.01. Granted, this doesn't matter-- it doesn't interfere with anything I'm doing, but I thought it was kind of interesting, and I could see how it could be a problem with slower machines.
