I have 190,000 contract no load from Mysql table onto a listbox. But it loads very slow. How can I speed up the performing.

Thanks in advance

190,000 options in a listbox will probably break any web browser. You should consider chaining the listbox with a higher-level control - grouping the contract numbers by region or city for example...

That best way to make something go faster is to not do it at all!

From a usability perspective, how would your users interact with 190,000 values in a drop-down list?

Even if you can fine-tune the database retrieval process to make it "fast", the bottleneck will likely your internet browser which may start choking at having to handle all those many values in memory in addition to the actual HTML document you're dealing with.

I would seriously revisit the design to implement something not necessarily easier to develop but absolutely more scalable and with a better user experience.

Perhaps you can break down you contracts into different buckets (groups, categories, etc.) and use some chained controls to load only the subset of contracts applicable to the category currently selected?

In some cases, you may need to go beyond what HTML Composer will let you do out-of-the-box and resort to third-party "widgets" that support lazy-loading via Ajax, for instance.
