Hi all, I have an iPhone app that has the needs to avoid inserting duplicate records, at first I thought I could just test each object in my in-memory array, create a fetch request for each object and test if it exists. But this is proving slow on the device, very slow (about 5 seconds, which is not acceptable). I have been trying to p...

To add 300 elements it takes around 10/12 seconds in Firefox(3.6) and IE(8), but opera does it faster. Please help me. Thanks, Kisor ...

I read on MSDN that to improve scripting efficiency, you can use self to make implicit window references explicit. Do you know if this is true? Does this basically mean that for instance calling self.location is somewhay more efficient than calling simply location with no window opject before? Since the MSDN text is referred to the sel...
Hi, I'm looking for benchmark data that compare the performance results between RMI call Vs. Web services call. The problem is that the customer give us target to meet less than 2sec response time for 3Mb XML size, using only text format xml. I'm trying to convince him that move to RMI interface as in this xml file size, no way that we ...
I have to run a select statement across several tables. I am sure the tables return different records. I am anyway using UNION ALL. Is it better to use UNION or of UNION ALL in performance terms when I am sure the tables return different records? ...
Hi, i'm building a site where we are considering to use a custom font (using @font-face) for all text on the site, not just the headers. I've already integrated a custom @font-face on another site for just the headers, which works fine, but i'm a bit worried about performance (especially rendering) when using a webfont for everything. Es...

I have a temp table with 13,000 rows. Most of the rows have a numeric price (100) but some are quoted in 32nds, i.e. 100-30 = 100 + 30/32 = 100.9375. (Some even have fractions of a 32th) I am opening a cursor FOR UPDATE and iterating over the temp table. It takes so long to execute, I am not even sure it is working (my DBA says the exec...
I just discovered that every request in an ASP.Net web application gets a Session lock at the begging of a request, and then releases it at the end of the request!!! I mean, WTF Microsoft! In case the implication is lost on you, as it was from me at first, this basically means the following: Anytime an ASP.Net webpage is taking a long...
Hi Folks, I'm wondering about access times on object members. More precisely, I'm benchmarking access times on the window object. I believe I can explain most behavior here on my own, but I'd feel better to hear some comments. Usecase: Different access times on different propertys ? I'm benchmarking on Firefox 3.6.8 (windows), the sim...
bug in my gcc? bug in my code? both? http://files.minthos.com/code/speedtest_doubles_wtf.cpp Somehow, it manages to "optimize" a function that results in the array of doubles being zeroed out into taking 2.6 seconds on my q6600, instead of the 33 ms the more complex function takes to fill the array with something somewhat meaningful. ...
