Dear Sasa Bojanic
First i would like to thank u for your fast response.
i am using shark 1.1 as you assumed because simply i can't use a beta
version (company policy).
i changed my code to use SharkTransaction and it really improved the
performance.i cerated 25 assignments and i got that result:
Assignment no 0 lasted: 94ms
Assignment no 1 lasted: 78ms
Assignment no 2 lasted: 110ms
Assignment no 3 lasted: 94ms
Assignment no 4 lasted: 94ms
Assignment no 5 lasted: 63ms
Assignment no 6 lasted: 94ms
Assignment no 7 lasted: 94ms
Assignment no 8 lasted: 93ms
Assignment no 9 lasted: 94ms
Assignment no 10 lasted: 79ms
Assignment no 11 lasted: 78ms
Assignment no 12 lasted: 125ms
Assignment no 13 lasted: 110ms
Assignment no 14 lasted: 78ms
Assignment no 15 lasted: 94ms
Assignment no 16 lasted: 110ms
Assignment no 17 lasted: 94ms
Assignment no 18 lasted: 78ms
Assignment no 19 lasted: 78ms
Assignment no 20 lasted: 94ms
Assignment no 21 lasted: 63ms
Assignment no 22 lasted: 110ms
Assignment no 23 lasted: 266ms
Assignment no 24 lasted: 172ms
time taken: 2537 for total
with shark1.1
which is an improvement but still not the desired performance.
i know that you will say use Shark 2.0.7 beta but as i said i can't use a
beta version according to my company policy also i downloaded shark
2.0.5beta but i does not have the swing admin interface and the batch
file (
runsa.bat).
