getline() very very slow on localhost on 5.X

[Martin Blapp]

Hi all,

Can someone confirm that this is still a problem on 6.X ? Something
is really broken here ...

FreeBSD 5.x connecting to localhost

time perl5.6.1 -MIO::Socket -e '$s = new IO::Socket::INET("localhost:110");
$s->print("user USER\r\n");
$s->getline(); $s->print("pass PASS\r\n"); $s->getline(); $s->print("LIST\r\n");
for ($i = 1; $i
< 2000; ++$i) { $j=1 + $i%500;$s->print("top $j 0\r\n"); }
$s->print("quit\r\n"); while (defined($_
= $s->getline())) { print $_; }' > xxx

real    2m9.509s

sys     0m0.184s
