Beta 11 to RC, now "ionic serve" is very slow

Hi Guys,

After upgrading from the beta-11 to RC ionic serve is incredibly slow. Comparing my simple beta-11 project to a fresh boilerplate tabs project the initial “ionic serve” start time is a few seconds slower (~30s) but making changes to any files (ts/css/html) is cripplingly slow.

In beta-11 modifying a ts file would take 3 seconds max for the browser to reload and modifying a html template in less than second. In RC both take 20-30 seconds, as if it’s rebuilding everything. Also, I occasionally get out of memory errors such as “FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory” with 6Gb of RAM which never appears to max out.

Is it just me? I can’t find any other topics raising this.

Thanks in advance :slight_smile:



@Sheepish same here. I’m waiting for RC1… I believe it will be better…

It’s not just you, I suffer from the same issues.

There is also a post and an issue about this

Aha, well I’m glad it’s not just me. Thank you @ecureuill, I’ll be sure to check Github too next time.
