Calypso loading code spinner

It is happening to me very often that to access the source of a
method, or sometimes to find senders/implementors, the Calypso browser
takes a long time to load it.

By long I mean from two to five seconds, sometimes longer.

I'm running Pharo 7 within a VirtualBox VM with Ubuntu 16.04 in a
Windows 10 host.

Regards,

Pharo 7.0.3

Answering myself...

It seems to be related with the power management because as soon as I
plugged in my laptop the spinning effect went away (and also the whole
environment got faster).
Maybe it has to do with the guest OS power management, although I
didn't see any noticeable slowdown in other apps within the VM.

Is there any specific PM thing in the Pharo VM? Or should I look at
the VBOX/Ubuntu settings.

Regards.

Hi Esteban,

This sounds like your host OS is powering down your laptop's HDD while on
battery, to save energy.  Plugging it in triggers a different rule that
selects "performance" over "energy savings" and keeps the drive up &
spinning constantly.

I would check the Win10 power management rules to verify this.  You can also
select a different power profile when on battery there, or create a new one
(such as "power savings except for the hard drive" when on battery).
