i wasn't sure which version of 23 i should try, so i downloaded
both 23.1 and 23.4.
`configure' for 23.1 ran successfully, but compilation failed:
$ make cd lib-src; make all \
CC='gcc' CFLAGS='-g -O2 -Wno-pointer-sign '
CPPFLAGS='-D_BSD_SOURCE ' \ LDFLAGS='-Wl,-znocombreloc '
MAKE='make'
make[1]: Entering directory
'/home/alexis/Downloads/src/emacs-23.1/lib-src' Makefile:144: ***
recipe commences before first target. Stop. make[1]: Leaving
directory '/home/alexis/Downloads/src/emacs-23.1/lib-src'
Makefile:325: recipe for target 'lib-src' failed make: ***
[lib-src] Error 2
`configure' for 23.4 required me to call `configure' with the
option "--with-crt-dir=/usr/lib/x86_64-linux-gnu". Compilation was
then successful. This version showed no lag at all.
(However, the alsamixer UI was severely broken, visually -
excessive line length resulted in line wrapping and blocks of
white background alternating with blocks of black background, as
per the attached PNG.)

Not according to the following, no. Having said that, i've not
manually made any modifications to the configuration in the
tarballs, or on master.
23.4:
CC='gcc' CFLAGS='-g -O2 -Wdeclaration-after-statement
-Wno-pointer-sign' CPPFLAGS='-D_BSD_SOURCE '
LDFLAGS='-Wl,-znocombreloc ' MAKE='make'
24.5:
CC='gcc -std=gnu99' CFLAGS='-g3 -O2' CPPFLAGS='' LDFLAGS=''
MAKE='make'
As for master, the env variables are no longer shown by the 'make'
process. However, running `make -n' produced lines like:
gcc -std=gnu11 -DHAVE_CONFIG_H -I. -I../lib -I../src -I../src -g3
-O2 -MT allocator.o -MD -MP -MF .deps/allocator.Tpo -c -o
allocator
Is that okay? Or can i find better information elsewhere?

Fair enough. One observation, though: the OP and i are both
running Debian Jessie.
