I’ve been using Google Chrome on my Macbook Pro for a long while, and I’ve noticed that some websites take some time to get moving along. In some ways, it feels like the browser is panting and trying to catch its breath. So today, while trying to solve a work problem I accidentally stumbled over a neat way to give my Chrome browser a little bit of a boost in performance. It seems to benefit when I use sites that are interactive, like my work help desk site or PNC online banking for example.
The trick is, create a small RAM drive on the system, and then copy the Chrome profile over, link to that profile so Chrome can find it, and then start to use Chrome. As Chrome works, things like settings and cache data go to RAM instead of the HD on my MacBook Pro. Then I use rsync to copy data into a backup folder just in case my MacBook pro suffers a kernel panic or something else that would accidentally dump the RAM drive.
There are a few pieces to this, mostly from scripts I copied off the network.
I copied the script called mount-tmp.sh and made only a few small adjustments. Specifically changed the maximum RAM drive size to 512MB.
Then I created two different bash scripts to check-in the profile to the RAM drive and then to check-out the profile from the RAM drive back to the HD. Since I wrote them from scratch, here they are:
check-in.sh
#!/bin/bash
/Users/andy/mount_tmp.sh
mv /Users/andy/Library/Application\ Support/Google/Chrome/Default ~/tmp
ln -s /Users/andy/tmp/Default /Users/andy/Library/Application\ Support/Google/Chrome/Default
rsync -avp -delete /Users/andy/tmp/Default /Users/andy/Library/Application\ Support/Google/Chrome/Default_BACKUP
echo “Complete.”
check-out.sh
#!/bin/bash
rsync -avp -delete /Users/andy/tmp/Default /Users/andy/Library/Application\ Support/Google/Chrome/Default_BACKUP
rm /Users/andy/Library/Application\ Support/Google/Chrome/Default
mv /Users/andy/tmp/Default /Users/andy/Library/Application\ Support/Google/Chrome
/Users/andy/mount_tmp.sh umount
echo “Complete.”
If you give this a shot as well, I would love to hear from you about your experiences with this little speed improvement hack! Hope you enjoy!
