Will El Capitan slow down my 2011 MacBook Pro?

[macness]

hey guys. A have a late 2011 i7 Mackbook Pro 13". I have never upgraded the RAM or SSD. I have done everything else under the sun to speed up my computer. It got considerably slower after Yosemite. Will El Capitan slow it down even more or is it just time to get a new MacBook? I was kinda hoping I could ateast wait until the SkyLake MacBooks

ElCap is fine on my circa 2008 MacBook Pro...

Slow it down? I doubt it, especially when El Capitan works quite well on my MacBook early 2009 model w/only 4 GB RAM.
