Which is the maximum upload size ?

The Java version has no predefined limit.

For the PHP version, there are two PHP configuration values that may need to be adjusted:

; Maximum allowed size for uploaded files. 
upload_max_filesize = 200M 

; Maximum size of POST data that PHP will accept. 
post_max_size = 200M

These values are normally changed in a file called php.ini. You may need to request your system administrator or hosting provider to change them. In some environments you are allowed to change them in a .htaccess file (per-directory web server configuration file). In such case this is what you should include :

php_value upload_max_filesize 200M 
php_value post_max_size 200M  

These examples assume a maximum upload size of 200 MB. WebbyFiles has been tested with files up to 1 GB of size.

How fast are the uploads / downloads ?

Under normal circumstances, the upload / download speed depends almost exclusively on network conditions such as your Internet connection speed or traffic load on the server. You shouldn't notice difference between WebbyFiles and FTP, for example.
