An App to monitor what process is causing disk activity?

[sabor]

I just bought an iMac 27" 4 cores, the one with the Intel i5. Sadly, this computer feels like my first iMac in terms of speed - it is sluggish and the reason for this is that the hard drive is being thrashed excessively.

By using iStat Menus, I can clearly see that the disk is being constantly read, constantly at 3 MB/s, which is insane since I am not copying anything:

I thought the culprit was Spotlight, so I turned off indexing on my main HD and the problem still persists.

I cannot find one utility out there that will let me know what process is beating the crap out of my hard drive. Is there such thing for OS X? Something like Windows 7 resource monitor is exactly what I am looking for.

Thanks!

Look in activity monitor and see what's doing all the reads.


post a screen shot if you can.

Thanks. How does one find what process on Activity Monitor is causing all the reads? All I can see is which one is using CPU and memory, but not Disk Activity:

Change the sort to %CPU. However, it looks like Mingler is the culprit.

Chnage the sort to %CPU. However, it looks like Mingler is the culprit.

Killed Mingler and disk activity continues, here are mu procs. sorted by CPU:

Looks like you have a virtual network running. That could be it.

Are you running VMWare ? is it up to date?

Also. Are you using speed download for some reason ? If you're downloading something that's gonna make the reads/writes pick up.

Not running VMWare at the time, it's up to date.

Mingler is still there, see the top entry.

Darn, spinnerlys beat me to it.

Also. You have a lot of apps running that do reads and writes.

That might just be normal for all the network types apps.

you have a number of applications open that could be causing the I/Os.

skype, tranmission, RDC, speed download can all be the culprit. i would try closing them down one by one.

whats the time there? apple scripts get run at certain times of the day too, dont forget - usually at 12am (midnight)

Mingler doesn't look killed when it's still taking 99.7% of the CPU.

Mingler will come back, it's part of a sync service skankwhore framework written by Apple. While it was killed, disk usage was still messed up:

Good idea, I'll close some of them and see if I find "the one".

I'd start with all your networking stuff. You have a lot.

Mingler is part of Mobile Me. See this thread for help:

There are others. I simply searched for Mingler and Mac and there were a number of threads about this problem. Maybe one will fix it for you.
