If you can't reconnect to your WiFi until you reboot your Froyo device, Wifix (lite) will probably help you. Just click the "Reassign" button, and about 8 seconds later you will be reconnected to your WiFi. You can use "Reconnect" if it doesn't work for you. There is also a "Keep Connection" checkbox that prevents your WiFi connection from been deactivated.
HTTP Bench is a small program to benchmark HTTP servers. This is the current feature set: iterating over a list of URLs; measuring response times and calculating min, max, and average values; measuring TCP/HTTP errors; multi-threaded operation for concurrent connections (using pthreads); setting an upper limit of requests per second; and validation of response strings. The source code is very simple.
