problem with webservices on win98

Hi , We are a group of Software Developer , currently developing a Budget Project using WinForms and XML Web Services by Visual Basic on Microsoft .Net Platform. When We run the project with an compiled .EXE extension , We discovered That The program is running quite slow (nearly 20 times slow) on Windows 98 rather Than Windows 2000 . If anyone has any idea What is the reason of It..? Another observation about Web Services ..When We call a function via Web Services, It works very slow on Windows 98.. Any solution to make it faster on Windows 98 or any setting to apply..?
