| [eclipse.org-committers] CVS performance - pserver access | 
From the "it can't always be us" dept.
A few of you have reported slow connection times to anonymous pserver 
CVS, especially when performing builds.
The reason for this is that a few of you have a broken DNS, where your 
IP doesn't reverse-lookup at all, or the reverse-lookup and the forward 
don't match.  This would introduce a delay of *at least* 30 seconds for 
your connection.
One project had this problem yesterday with their build server in 
Turkey.  This morning their DNS is fixed, and their connection time went 
from 32 seconds yesterday to 0.38 seconds today. While in Turkey I 
tested CVS, website, downloads and bugzilla performance.  All were very 
responsive from across the pond. Thanks Naci for allowing me to test all 
this!
To test your DNS, please log in to Committer Tools [1] and hit the Test 
my DNS link. I reconfigured pserver to be less strict with the lookups, 
but I cannot remove them altogether because I need to enforce 
domain-name restrictions on specific domains. And no, I'm not about to 
start maintaining your broken hostnames in my hosts files.
Here are some of the broken hosts from yesterday's log. I have 
*hundreds* of entries from some of these hosts:
