I installed the wallet (0.8.7) on my Mac. Synced within 20 minutes, all good. Trying to do the same on my Ubuntu 14 (on an lenovo x220, with ssd), and
it takes ages to sync (not the issue I am raising.. I am aware this problem has been discussed before) (rate is of a couple of blocks per minutes)
the whole system becomes irresponsive when I run the wallet. I.e., I can't browse or open a directory without having to wait 25 seconds etc.
I don't have to face slow downs on my machine when the Ethereum Wallet is not running. So what could be happening and how can I fix it, please?
