Hi everyone - hope you don't mind me jumping on this question with a related issue
I have recently purchased a macbook pro 2.8 intel core i7 4gb ram 1333 mhz ddr3 lion 10.7.4 I have used the transfer my mac utility from my older macbook The issue I'm having is that some of the apps are VERY slow - much slower than the old macbook (albeit i did max the ram on that unit). Preview in particular is the worst offender. I have done the obvious - used disk utility to repair permissions and with a 750gb drive with loads of space on it, I can't see anything that is an obvious factor. My web search indicated that sophos may be slowing it down. Would appreciate any suggestions, many thanks in advance.... (and Ronnie, pls don't stop whatever you are doing to be first to reply ;) Best regards Justin Davies On 22/06/2012, at 11:35 AM, Ronda Brown wrote: > Hi Adrian, > > Something you could try is: > Open "System Preferences > General" and uncheck the “Restore windows when > quitting and re-opening apps” option. > > People have had success with streaming video in Lion by doing the above. > I have not experienced any problem with streaming video in Lion BUT I have > always had this setting UNCHECKED! > > The suspicion is that the background task that takes a snapshot of the memory > and system state for each running application is failing behind in taking > snapshots when large amounts of RAM are updated. > > In video streaming by definition the application memory is undergoing large > frequent updates. > If the suspicion is correct, then instead of dropping work items the snapshot > application is trying to process an ever-increasing list of work. > The result appears to be CPU starvation to video playback. > > Cheers, > Ronni > > 17" MacBook Pro 2.3GHz Quad-Core i7 “Thunderbolt" > 2.3GHz / 8GB / 750GB @ 7200rpm HD > > OS X 10.7.4 Lion > Windows 7 Ultimate (under sufferance) > > > On 22/06/2012, at 11:16 AM, Neil Houghton wrote: > >> Hi Adrian, >> >> I gather from your previous emails that the problem is just with streaming >> YouTube - rather than already downloaded video. >> >> Forgive me for asking the obvious - but you have checked your internet >> connection speed to make sure that you have not developed a problem in that >> area? >> >> >> Cheers >> >> >> >> Neil >> -- >> Neil R.
