Refresh HTML Page Every 5 Seconds Usages META tag

How to Refresh HTML/CGI page every 5 seconds?
Today I was searching for page refresh after a certain activity is completed. I was running some task in say CGI 1; which uses fork() to execute another task; once this task is done CGI 1 should get refreshed or should show me the updated status which is being updated by new task.
I tried lot of other combination like calling refresh function from new task; with window.opener.refresh_fucntion(); and a lot.
Finally got the solution using meta tag of html.

Meta HTML tag,The element provides meta-information about your page
And the answer to question is just include before head element this tag;
Refresh page every 5 seconds:

Refresh page every 5 seconds:

<meta http-equiv="refresh" content="5" />

and my job is done.
Thanks to meta tag.

Linux SMB write performance With Simple Tips

SMB write performance can be increased by Tuning the buffer cache. The secret to good performance is to keep as much of the data in memory for as long as is possible. Writing to the disk is the slowest part of any filesystem. If you know that the filesystem will be heavily used, then you can tune this process for Linux Samba. writing out dirty blocks to the disk until the filesystem buffer cache is 80 percent full (80). default is 40%, source = http://tldp.org/LDP/solrhe/Securing-Optimizing-Linux-RH-Edition-v1.3/chap29sec287.html by writing echo 80 > /proc/sys/vm/dirty_ratio I am getting around 2MB increase while write operation, tested in Xp. I have tried with this single option, as the ref source is for linux 2.2 and we are using 2.6 kernel. we can try out Linux General Optimization suggested at http://tldp.org/LDP/solrhe/Securing-Optimizing-Linux-RH-Edition-v1.3/gen-optim.html Tried with smb.conf, I am getting around 1MB gain while read and write. socket options = TCP_NODELAY I...
