They probably aren't slow on a machine level, they are probably slow to boot because of a shit group policy structure they are running. 

I was the Sysadmin for a school district for 3 years until march of this year, I'll tell you a little story about school districts. 
 
Most of the people in charge don't know nor care about technology and what it can bring to the classroom. 
 
Budgets are very small in most cases, my district had around 2000 students and my tech budget for the year was $75,000 USD. This was used to upgrade PCs, projectors/bulbs, things that broke, interactive projectors/smartboards buy software licensing and add PC/iPad for the kids to use. budgeting comes from how many students and families in the districts area, and what is bad about is that the more tax paying people there is in the area the LESS money the school gets from federal funding. A lot of times levies do not get passed so the school has to resort to higher school fees to fund itself. It's very hard for schools to even AC their buildings(if they are older), let alone replace PC's every three years. 
 
The problem is that kids like to mess with things and that is what screws them up. We took the policy that if YOU the student broken something and it was still usable(DVD drive rubber bands) we were not replacing it and you still got punished. 

10% performance increase nothing to really be excited about

Highly recommend the LG G4, I have had mine about a month and it has been wonderful. Camera is great! Overall the phone is very responsive and I love that I can put an SD card in it for all my music.
