Banner day for Polls

From Fred Vu. Look at the stats that Polls gets :

On Wednesday, Polls recorded a banner day:
= 54MM web server hits
= 52MM polls requests (Q&A and Results)
= 11MM votes.
= 812 slow responses!!!
= Traffic highlights, 2100+ requests/sec for a period of 10 minutes,
2000+ requests/sec for a period of 20 minutes, 1800+ for 3 hours,
1200+ for 5 hours!!!
= 99.95% availability!!!
= Analysis based on 2 server logs, average response time was around 73 ms per request at peak hours!!!!

This is the result of collective efforts from various teams who are committed
to "fix" the system after last year's melt down at ..... 1700 reqs/sec. Kudos to
everyone who contributed to this momentary glory :-) At this point, I can safely
say the system can handle 2100 reqs/sec with ease, how much headroom it has?
We will find out when the next big hit strikes ;-)

P.S. - Journals Team, don't know how long this has been in place, but I love the new "Add a Comment" interface. :-)

Wow!! Polls just keeps improving in terms of traffic and capacity :-)

Based on a long history with this project, I'd be very interested in knowing how the system was improved to achieve these new records.

In Memory: Leo Pot

Today is one of those days that feels "empty" or "numb". I attended a funeral for Leo Pot, who died on July 4th from Cancer. Such a nice man, very successful with his businesses, and a great family. Funny, sharp, witty. He shared a glass of wine or two with me, and gave me thoughts on life after leaving my last job. More important, he has a wonderful family. It's hard seeing his 3 young daughters at the funeral, each dealing with grief. Live each day to the fullest. Make sure you get the most out of what you do, and spend time with people you care about. Rest in peace, Leo. "On July 4, 2008 Leonardus Leo Josephus Pot, loving father and doting husband, left his earthly existence peacefully, at home, in the company of his family. Born in the fall of 1956 in Oegstgeest, The Netherlands to Martin and Joanne Pot, he would go on to complete a Bachelor's deg...

AOLers : Don't let people say silly things about your company

Don't let people say silly things about your company Yes I mean it. Your company. I read the blogosphere, and often see articles on some feature or product that has been launched. Then I follow the comments. You get the normal AOL bashing, some people who like it, some people who bash and have never used the product being reviewed. All the normal stuff. But Frank Gruber set an example for me last year. When he spots these comments, he follows up with a comment and (if possible) contacts the person who wrote the it. Often the comments don't have contact info or use real names. But if they do, Frank will email them as follow up. And the response is normally good. If Frank can do it (as busy as he is), so can we all do it. The latest blog that struck me was this article " Yes, People Still Use AOL " on Silicon Alley Insider. The first comment was negative, the third was negative. ...

Pizza - with egg on it? A Paris delight!

Tonight at a late night snack after lots of walking, pizza... And boy did it taste good. I have never had pizza with egg on it, until in Paris. But though it looked a bit odd, it tasted yummy. What's on your pizza? Tags: pizza , paris , france
