Slow mounting time for 1TB RAM disk
2 posts · Closed
Hello. We are interested in evaluating your RAM Disk product. We are currently using it, but noticed that it takes about 10 minutes to mount a 1TB RAM disk.
We would like to use this as the SQL TEMPDB drive. I've tried using an .img, and without using one, but it still takes time. We have this currently set to mount at boot. What is the optimal way to get this mounted faster? I've added antivirus exclusions and hibernation has been turned off as suggested.
From your message, it is not clear whether you are using a 2 TB RAM Disk (as specified in the subject) or 1 TB RAM Disk (as specified in the message), but 10 minutes is a reasonable time even for 1 TB.
Even though everything takes place in RAM, the driver needs to allocate and zero-fill a 1 TB chunk of memory. Dividing 1024 GB by 600 seconds (10 min) reveals that the driver allocates and zero-fills 1.7 GB/s upon initialisation. I am afraid it cannot be made much faster than that.
