When will you have enough performance?

Guest Author
For someone who never had a web-page, this blog business is really
frightening so bear with me if I seem like a novice. I wonder if
someone actually reads these pages or its just the robots, crawlers
and zombies generating the hits ;\^) Anyway since Carol (our PM) thinks
this is useful medium to tell people outside Sun what I am thinking
instead of them finding out when the product actually ships, here
goes.

My name is Sunay Tripathi and I am a Sr. staff Eng. in Solaris
Networking and security technologies. Yes, we are the people who make
the 'Net' work in 'Network is the computer'. I also go by as the
architect of FireEngine, the new TCP/IP stack in Solaris 10 for people
who have tried Solaris 10 already and are pretty happy with the
performance (which is most).


So what am I working on these days - well I hear 10Gb is
happening. And I also hear that 10Gb is not enough. People are wanting
20-30Gbps bandwidth coming into 4 CPU opteron blades and still have
meaningful processing power left!! Well, you do that and watch the
interrupts go up like crazy and the system behave in more twisted ways
than you can imagine and trust me, its not nice. But FireEngine comes
to the rescue. We can tame the interrupts and do exactly what people
want. I'll tell you the details some other day unless John Fowler can
beat me to it by blogging soon.

Fairness and security is something that keeps me awake these days. A
large section of customers tell me that they see 'http' literally
disappearing in next 3-5 years and everything will be 'https' (SSL)
and they don't want to sacrifice CPU just doing crypto and they don't
want crypto to overwhelm rest of the traffic. Well, OK, they said QOS
but what they actually meant was fairness without any guarantees. I am
hard pressed to see why CNN will go 'https' but they do have a point -
Yahoo mail should really be SSL protected by default!! So I am building
fairness as part of the architecture instead of another add-on
layer.

So let me tell you what else do I do other than designing and writing
code. I like to hang out with my old stanford and IIT buddies who keep
telling me that how we can combine forces to build the next big thing
for internet (some day). I also love watching my 11 months old learn
to walk. He is already hooked on to my workstation and has his own
desktop now. Not surprising given that he sees his Mom and Dad spend
80% of their waking hours on these things. But what he really wants is
my Acer Ferrari laptop running 64bit Solaris and I tell him dream on
buddy :) My other passion is fast cars (after fast code) and
Taekwando. I am a black belt and used to practice with Stanford
Taekwando. Had a string of injuries last year which has kept me away
but I have started training again and will be back soon.

Well, thats who I am. But let me tell you the real reason why I am
doing this (apart from the fact even Sin-yaw and the rest of the perf
team has a blog) - I actually want to hear back from you guys. Tell
me what latest and greatest thing you are working on or dreaming off
and how Solaris can make it happen for you. Not sure how the feedback
thing works on this blog but you can always drop me a direct
email. The address is pretty simple - sunay at sun dot com. I would
also love to hear your opinions if you already tried Solaris 10.

And as for when will you have enough performance? The answer is never!

    I think the coolest idea that I have had is software Raid0 or what ever raid level USB sticks or drives. Why has this not happend? maybe it is a hardware limitation? I dont know. This would increase the size of usb sticks and you could improve performance. limited security since the drive is usless without the other. (phisical)
