gsa is very slow most time.

is search engine bottle neck? so lot of proxies will help a lot for overall performance of gsa?

or use many different search engines and the program should have enough to do.

BOTH work right?
i have 10 projects,  how to set option for all projects by once? 

You can export your options and then import them for each new campaign

it is problem 10 times workload..

GSA is pretty easy to setup, you can't setup 10 projects with two mouse clicks. Your best best is to setup a new project is to import the settings that you saved from another setup like you want.

gsa runing at remote pc, it is not fast to operate.

If your connection to your server (remote PC) is slow, causing it to be laggy and annoying to setup campaigns etc, remember that the GSA licence is a PER ACTIVE Program licence, not per install, so you can also install it on your home pc, just dont run both at the same time.

That way you can set up all your projects on your home pc (no lag), export the details, close GSA, then upload to your server, and import all the details in a few clicks.

thanks,  it is better, but i still need to import 10 one by one?
i found gsa store project info at c:\user\somefolder\gsa
can i just copy such file to remote pc?

1) stop all projects -> highlight all your edited projects -> right click -> modify your project -> backup

2) transfer this file to your remote pc.

3) stop all projects -> right click -> modify your project -> restore

thanks, it is more easy.
