SugarCRM Changing Max file Upload Limit

In sugar while uploading a file as attachment to e.g Marketing->Accounts->youraccount->Create Note or Attachment.
I tried to upload a file size 20M, it did not attached and no error message as well. Here is to fix this.After doing the following changes, performance of site also improves.

Step 1: Change in SugarCRM
Go to Admin->System Settings->Advanced
change Maximum upload size e.g 41943040 (40M) default was 3000000 (3M)

Step 2: Change in php.ini file
Login to your server hosting the site,
Go to /etc/php5/apache2/php.ini and change the following, Max, limit 40M

       post_max_size = 40M
   upload_max_size = 40M

   max_execution_time = 1000
   max_input_time = 60
   memory_limit = 128M

imran@venus:/var/www/sugar$ sudo nano /etc/php5/apache2/php.ini

;;;;;;;;;;;;;;;;;;;
; Resource Limits ;
;;;;;;;;;;;;;;;;;;;

max_execution_time = 100 ; Maximum execution time of each script, in seconds, 30s default
max_input_time = 60 ; Maximum amount of time each script may spend parsing request data
;max_input_nesting_level = 64 ; Maximum input variable nesting level
memory_limit = 128M ; Maximum amount of memory a script may consume (16MB), change to 50M, 50M defau$

;;;;;;;;;;;;;;;;;
; Data Handling ;
;;;;;;;;;;;;;;;;;
;

; Maximum size of POST data that PHP will accept, 8M default
post_max_size = 40M


;;;;;;;;;;;;;;;;
; File Uploads ;
;;;;;;;;;;;;;;;;

; Maximum allowed size for uploaded files. change sizd 2M to 10M, 10M default
upload_max_filesize = 40M

Save the file and exit.

Step 3: Restart the apache2 web server
imran@venus:/var/www/sugar$ sudo nano /etc/php5/apache2/php.ini

Step 4: Test the upload Limit
Go to Marketing->Accounts->youraccount->Create Note or Attachment.
and attach a file e.g 20 M, it should be attached now.
