  • Performance optimization for mssql: decrease stored procedures execution time or unload the server?

    - by tim
    Hello everybody! We have a web service which provides search over hotels. There is a problem with performance: a single request to the service takes around 5000 ms. Almost all of the time is spent in database by executing storing procedures. During the request our server (mssql2008) consumes ~90% of the processor time. When 2 requests are made in parallel the average time grows and is around 7000 ms. When number of request is increasing, the average time of response is increasing as well. We have 20-30 requests per minute. Which kind of optimization is the best in this case having in mind that the goal is to provide stable response time for the service: 1) Try to decrease the stored procedures execution time 2) Try to find the way how to unload the server It is interesting to hear from people who deal with booking sites. Thanks!

  • Ruby on Rails - can't access datetime model object

    - by NomadicRiley
    I've created a model that has 3 string columns and a datetime. Everything is running in SQLite3 and I can view the records in my table just fine using Lita. I'm trying to display the values in a page (index action) using code like this: <% @details.each do |lifeCycle| % <%= debug(lifeCycle)% <%= lifeCycle.lifeCycleId % <%= lifeCycle.eventType % <%= debug(lifeCycle.timeId) % <% end % From the debug I get a result like this: --- !ruby/object:LifeCycle attributes: eventType: Order created_at: "2111359287.23037" timeId: "2455364.89983796" eventId: "98765" updated_at: "2111359287.23037" lifeCycleId: "12345" id: "1" attributes_cache: {} But whenever I try to access the event timeId - i' getting a nil value. This is true if i try to run debug on just that field debug(lifeCycle.timeId), or call a function on it. Is there something obvious I'm missing here?

  • Cancel the calculation if input-mismatch was found

    - by Lert Pianapitham
    Hallo everybody, i have programmed a sub procedure, that will be called in the main procedure (called by event of mainForm), to valid the inputs before the main calculation. now i'm searching for a method, how can i cancel the calculation and refocus the mainForm if some inputs mismatch. i think, it's unnecessary to use the Try-Catch statment to trap the error from calculation because i know what is its source and it should be prevented due to the code preformance. Has someone an idea to due with this? best regards Lert Pianapitham
