HTML table extraction slow and times out

Hi,
I fill a form and on submission I get a HTML web table that has 20 columns and 2877 rows. If I would have increased the date range in the form then this table would have a lot more rows. My problems is that extracting cell by cell (!replayspeed is FAST) results in a timeout after 900s.
[error] macro timeout 900s (change the value in the settings if needed)
My issue is, if it takes 15 minutes only for 70 rows then I will never be able to use this method to get 2877 rows! Can the team help me use a faster and reliable method to extract the entire table in hopefully under 5 minutes.
I am attaching the code for your reference.

Can you send this table to us (team AT a9t9.com)? Maybe there is indeed a performance issue for huge tables.

Question: Do you need to extract the complete table or only certain cells?

Hi,

The website was down last night. I did not understand how will it be possible to send only the table across to the support team since the website is essentially a form that generates the table when the proper inputs are submitted. There are only 4 fields that need to be filled. Below are the details of how to generate the table.

Open 
https://www.indiabondinfo.nsdl.com/bds-web/advancedSearchRequest.do
1. Type of Instrument:   select both Bonds + Debentures
2. Instrument Status:    select both Active + Matured
3. Date of Allotment     From: 15/11/2017   To:   15/11/2018
4. Click [Search] button

The complete table of 20 columns x 2877+ rows needs to be extracted.

Hi,
Were you able to pin down the cause of the issue, as to why Kantu is unable to extract very large tables and times out. I have again faced the same issue with another (similar) usecase too.
