In the process of testing our MRP and the run time from 10.1.500 has gone from 2hrs 45min to 6hrs 15 mins. Using the same settings to run MRP 2 processes 3 Schedulers. Don’t understand what has changed to make such a performance difference especially when we are on better hardware. Does anyone ha…

What type of hardware upgrade did you make? Epicor MRP is not multi-threaded… we once had a multi-threaded processor and it was slow… and then we simply went to a 4ghz processor that barely had any cores/threads and boom MRP was fast.

@hkeric.wci It is supposed to split the records and run many single threaded processes to reduce the time… [image] E10 BPM Threading Epicor ERP 10 I experimented with multi-thread within the product configurator, and found it was possible, but it was a challenge. One thou…

Thanks for both your replies. Current hardware we have Xeon E5-2690 v4 2.60GHz New Hardware Intel® Xeon® Gold 6226R Processor 22M Cache, 2.90 GHz We have changed the processors from 2 to 4 and schedulers from 3 to 6 and that has changed it to 3hrs 40min which I think will be OK. Just wanted to …

I have seen/heard of situations where MRP all of the sudden takes longer for “no apparent reason”… but typically, once you dig deep enough, it can be figured out. You might try adding more processors (change 2 to 4, or 3 to 5)… do it one day at a time to see what matters. But sometimes adding a new…

One “solution” to this problem is to break up your sales into a variety of part numbers. In an ETO environment. For example, one company I know of used the product configurator… but all the configured parts came out with the same part number “truck”… which caused MRP to run slow. But instead, they m…

I’m definitely not a SQL Index expert so please forgive me if I am totally wrong here but…I personally feel like Epicor needs to take a look at and revamp their Indexes on the Tables that are used in the MRP process. I believe there are WAAAY too many indexes and WAAAY too many fields on each index.…

Nice post Heather. While there are deadlocks on the SQL side, is it due to the application side not being coded optimally? I am neither a SQL guru nor a developer so I don’t know what kind of tools could be used to look at the application side, but there are no doubt some SQL best practices that se…

Hi Heather First of all wow great post, I am far from an expert in this field but like you learnt a lot from Brent Ozar. I agree I feel it is an area Epicor need to work on and hopefully, everyone who reads this will vote for your Epicor ideas suggestion to Speed Up MRP https://epicor-manufacturin…

I honestly can’t answer that about Epicor’s programming or design. All I know is I’ve witnessed Brent O. significantly performance tune some pretty bad SQL Queries just by adding the appropriate indexes - if there weren’t any on the table(s) (not usually more than 5 indexes with approx. 5 fields eac…
