Poor performance in Europe

in reply to PerlMonks Server Move

I am not sure what is causing this, but the refresh rate has gone up to 20-30 seconds for me from Switzerland. I asked around the Chatterbox and virtualsue report that performance is down for her too. Refresh time used to be 5-10 sec.

When I go to pair.com , they come up right away, but the perlmonks site is really sluggish at all hours of the day, from work, from home on cable, and from 56k modem. Something seems to be messed up. The time for this page to appear again on preview was 20 sec.

It is possible that this is transient, but the performance seems to have settled in.

I have not had a chance to run an iproute test to see what the hops are.

I guess you're still working out the bugs so I'll wait a while longer to see if it gets better - Jsut thought you might want to hear back.

I'll keep an eye on performance and report again later.

    No reasons for Europeans to feel singled out. I'm getting 20+ second refreshes in California.

    I don't think its the network:

    The slowest part there is likely to be between me and the first router :)

      I'm not seeing anything obviously untoward from Silicon Valley to Pittsburgh (and I'm still seeing 20+ second refreshes).

      We may be discovering what the backup schedule is for the new server. :-|
