Are you running other software too? Your specs seem more than enough for zcashd. ---

If I start a new node, it is quickly.Once I import the backup wallet, it becomes rescan and never end. ---

Rescanning will use a lot more resources and like Hanh aluded to you might turn off unecessary programs like web browsers. What OS is this on? ---

Once I import the backup wallet, it becomes rescan and never end. The same problem also happened in importing a address private key. ---

Thank you for your sincerely reply. Starting a new node, and import a single address private key finally worked. ---

Last night I decided to try out the new [multi-threaded batch trial decryption improvements](https://github.com/zcash/zcash/pull/6088) so I compiled a zcashd from git, took an old wallet with plenty of addresses/UTXOs and did a `-rescan`. Looks like it managed to finish in five hours: ```auto 2022-07-23T03:56:56.716641Z INFO Init: main: Still rescanning. At block 542630. Progress=0.153382 ... 2022-07-23T08:50:26.002623Z INFO Init: main: Still rescanning. At block 1739545. Progress=0.995290 ``` ---

ZecWallet Light also freezes for me. I wouldn’t recommend it at this point. YWallet does work however. ---

For ref, I turned off the notebook last night and rebooted this morning. Here is how long it took me to catch up to the current block height: ![Screenshot_2022-07-24_11-37-20](https://global.discourse-cdn.com/zcash/original/3X/e/1/e1763f08c80c149bc5d1b2212c26343d8221b0d1.png) Much faster than with 5.0.0 kudos to all the hard work in the background. 👏 ---

If I understand correctly, it took you ~3h to catch up on ~8h of blocks? ---

Yes. Cold hard numbers, nothing special with my setup (wifi in house). Would be neat to get data from others 🧐 ---

Ok - I was a bit confused because 2x real time doesn’t seem fast. It is faster than before though. [Previous page](https://forum.zcashcommunity.com/t/rescanning-wallet-a-week-and-progress-is-moving-backward/42576.md?page=1)
