IO speed slipping again?

[Jerry Quinn]

Hi, all.  For a little while, the mainline library has been giving
output speeds close to gcc 2.95 (within 10-20%).  Some time in the
last week or two, the library slowed way down again.  Do any of you
know what might have happened?  Fallout from Paolo's work?  If not,
I'll try to do a search and locate the patch.

If it's a correctness issue, then I'm likely to be out of luck, but
...

This is the simple test of writing ints and newlines to a file I've
been using to work on the cache stuff.

jlquinn@smaug:~/gcc/test$ g++dev -O2 fstreamtest.cc
jlquinn@smaug:~/gcc/test$ time ./a.out
 
real    0m11.055s
user    0m10.550s
sys     0m0.480s

jlquinn@smaug:~/gcc/test$ g++-2.95 -O2 fstreamtest.cc
jlquinn@smaug:~/gcc/test$ time ./a.out
 
real    0m4.038s
user    0m3.540s
sys     0m0.460s
