Ubuntu Lucid too slow to boot?

Check if you have FAT or NTFS partition...presence of FAT/NTFS partitions can cause 'fsck' to run at every boot causing significant delay in the boot speed. Following are the entries that I find in my /etc/fstab:
proc            /proc           proc    nodev,noexec,nosuid                  0       0
/dev/sda1       /               ext3    errors=remount-ro                      0       1
/dev/sda6       /data           vfat    defaults,umask=007,gid=46      0       1

All you need to do is to change the last parameter value in the FAT/NTFS entries from 1 to 0. The last parameter indicates whether the system checks for the file system during boot. 

With this change, my system just takes 40.6 seconds to boot as opposed to 2 minutes 6 seconds earlier!

This is just one reason as to why the boot could get slow. In any case it is best to run the 'bootchart' tool that captures information on the processes run during the boot [just google to get more information on the bootchart tool]. 

You can also press the ESC key as soon as the Ubuntu boot screen starts... to know messages coming out of the boot.

New to TXSeries, TX Series, TxSeries. Txseries, TXS, TXSeries/CICS.....?

Hmm... probably the first thing to know if you are new to TXSeries, is how to search for relevant materials/discussions on the web!

There's a lot of documents on the web that has mis-interpreted the name of the product with some of the variations you could see in the title of this blog itself! When I do a Google on "TXSeries" it's always the standard information from the product's site... I don't tend to see any discussion out there in the community, but a small tweak to the name, like "TX Series" +CICS produces some amazing results... give it a try!

I guess, the correct representation of the product name is "TXSeries" (the first three letters in capital) ... or to be more precise "TXSeries for Multiplatforms" as seen in the IBM's site.

So few tips if you are searching for any content related to this product. Use different variations of TXSeries like TXSeries (the correct one, unfortunately with less search results), TX Series (the most commonly used 'incorrect' representation), and so on. And a magic happens, and your search results gets more precise if you include the "CICS" word in your search.

I have heard this product getting referred to other names like CICS on open systems, CICS on distributed platforms, CICS open, CICS 6000, CICS on AIX... So if you are not finding any results with your searches, you might want to include some of these terms and try again.

If you still can't get relevant search results, may be that's something not yet discussed on the web, so you might want to try discussing it here: TXSeries Forum

So, happy searching! and you have learnt your first lesson on TXSeries!
