Some of my colleague and friends asked me to write post on performance tuning .I was busy on some development project so I didn't get time to write a post. Performance is one measure on which we rate anything, suppose I have developed product it has all feature which satisfy any business need.It gives accurate prediction . I want to sell that product in million dollar but If I say for accurate prediction you only need to wait .Then buyer will straight forward say "Sorry not interested " .Now days life is fast no one wants to wait .They need result on the fly so if your product is so good but very low performance then no one will buy it.
So performance is key factor for any organization to get fame in the market.Suppose company developed product and sold to local customer.Starting time customer was very happy with result ,response and services from the company.Now customer expands business to all over India .So company will charge more money from them for support.They will happily give it with some negotiation.As the business expands customer will start facing issue with response i.e. performance.They will say initial time we was getting response in millisecond now we need to wait for 1 minute .So response time is increased by 60 - 100% .Then situation will become very worse for company .System was originally tested on database whose size varies between 1 - 2 GB. Now data size growing drastically i.e. it is flowing in TB . So response time what there are getting is correct only interesting thing everything is working as expected .It will work as expected if they have proper deadlock management and blocking mechanism.
Thing is how you face your customer now.They will force you give us solution to resolve performance issue .Now they are more dependant on you .So this is time to get fame and name in the market.Making customer happy is always healthier for company financial growth.
This is time to think something bigger which you have not thought while system was developed.How will you make customer happy in this case , if they got good response from application they will be happy.
This is just introductory post I will start technical things from next post which we can use to increase performance .
