One thing I've noticed with 25.0.92 and OS X is that Emacs 25 can be very "pausy". That is, I'll do something (even just switch buffers), and suddenly Emacs is locked for about 5-10 seconds, with absolutely no indication before or after of what is happening. Maybe it's GC? Especially with ERC, this is quite noticeable because it happens in the mid= dle of a conversation. In Emacs 24 I never experienced this much stalling (just= a little bit). However, this has been impossible to track down thus far; but I wonder if w= hat you're seeing is at all similar. --=20 John Wiegley GPG fingerprint =3D 4710 CF98 AF9B 327B B80F http://newartisans.com 60E1 46C4 BD1A 7AC1 4BA2
