How to get to the bottom of the spinning beach ball when first entering Pharo
Hi guys - this has come up before in the past - but Iâm really noticing it now having worked on a project for a few weeks. Every time I go into my image (by go into - I mean unsuspend my laptop and start using as its the current app, OR flipping to it from say reading email) I get a shining beach ball for 5-10 seconds and then the app is responsive and I can work on it. Itâs not all of the time, but Iâve noticed its not just my laptop warming up - as several times a day I see it when flipping back to it. How do I trouble shoot what is going on - does the system reporter tool tell me anything useful? I did notice my image has grown quite large - is it just that?

Tim I have never seen a spinning beach ball, but I often find, when coming back to Pharo after using some other application, that there is a delay of a few seconds, during which time I see the standard Windows 'hang on a bit' signal, which is a blue ring near the cursor. My assumption is that this is the effect of swapping from virtual memory - my machine has only(!) 4GB of real Ram. Could the beach ball be something generated by your OS in a similar situation? - which OS are you on, by the way?

Hi Peter - yes the beach ball is the mac equivalent of the spinning circle , but it seems to appear more often than I expect - just web browsing or reading email and then flipping back incurs that sane delay? This is on a 16gb MacBook Pro. I donât recall this in Pharo 6 the same, but Iâm doing more hard core development on 7. I did look in the process browser and find an odd looking process that wasnât in my other images, so I terminated it and will see if maybe it was that. But I think Iâve seen it in other images too (Iâm not sure). Iâm wondering if others notice this - however it seems like you do too. Tim Sent from my iPhone
