Hello I have a long-term problem with loading of packages. Compilation takes very long time on my Windows PCs. On desktop it takes "only" double amount of time in comparison with linux, but on notebook, it is more than 10 times slower. Desktop has Windows 7 Ultimate 64-bit and notebook PC with Windows 7 Home Premium 64-bit, both have somehow similar specs (4-6 years old dual-core processors on 2,9 and 2,4 GHz), similar software, both have magnetic HDDs. I believe it used to take very long time on my notebook too, but I tried opening Pharo there again and it was somehow OK, but I'm not aware of any major change which could have caused it ... I mean... a lot changes on my PCs, but I can't remember anything which could directly affect it. Following "benchmarks" are both on same (copy paste) of VM - Windows VM 453 from 2015-06-18. Both on clean image 50141. All tested in as much as similar conditions as possible with everything else (possible) turned off. However, it used to be slow like that for a long time on multiple previous VMs and images since I can even remember (which is about a year).

I will appreciate any help. Jan -- View this message in context: http://forum.world.st/Slow-compilation-on-one-of-my-Windows-PCs-tp4834668.ht...
