Magento Rebuild Catalog产品全文搜索索引锁定表

We have 4 stores, catalog products 80000+ when I do indexing of "Rebuild Catalog product full-text search index" it runs for 30 min and then breaks due to lock of tables.

the site is also very slow.

cache is enabled.

How can I do full re-index in a faster method? Any solution/suggestion welcomed

This process is really slow and there is a good free extension with the explanation :
