Pinning 7 tabs reduce performance?

[kat.hayes]

I have 7 tabs pinned in Safari and it seems like the performance of my MBP has gone down sine doing this. I cleared history, quit Safari and rebooted and it is a bit better, though my fans are going off right now with nothing else open except one tab in Chrome of email. The pinned tabs in Safari are just pages from an online store.

Is there any reason that pinned tabs should use more memory or require more resources?

Thanks

Are the tabs really resource-intensive type sites? I wonder if Safari more aggressively updates pinned tabs.

If you open Activity Monitor, you should see separate entries for each website loaded. Looking at mine (below), I see that my inactive tabs aren't incurring much cost, but I'd imagine you could play around with pinning/unpinning sites and see if that affects their processor usage, etc.

They are just pages from an online store, they do not seem resource-intensive at all. I will check out activity monitor and report back, thanks.
