Or you can immediately increase the logical size of the IRISTEMP to the desired value, for example: %SYS>set status=##class(Config.Databases).Get("IRISTEMP",.props) %SYS>set status=##class(SYS.Database).ModifyDatabase(props("Directory"),5*1024) ; 5GbIn this case, you will immediately increase the size from 240Mb to 5Gb, bypassing many small expansions.

go to post Vitaliy Serdtsev · Jun 11 Unlike SQL, which has hints, IRIS Object Script has nothing similar. The only thing left to do is to tweak these settings. If you already have everything tuned, then probably the only thing left is to contact the WRC. PS: Having a reproducible example here would be a big help with the experiments. I love detective problems like this :)

go to post Vitaliy Serdtsev · Jun 9 Let's suppose two different routines use one and the same chunk of code. From the object-oriented POV, a good decision is to have this chunk of code in a separate class and have both routines call it. However, whenever you call code outside of the routine as opposed to calling code in the same routine, some execution speed is lost. For reports churning through millions of transactions this lost speed might be noticeable. Any advice how to optimize specifically speed? What you are asking is very similar to Inline function in C. In Caché, macros and/or preprocessor directives are great for this role. Especially if the code size is small: ObjectScript Macros and the Macro Preprocessor In this case you will avoid the overhead of calling goto, do, job, xecute, etc. Example (procedure "swap") Class dc.a Extends %RegisteredObject { ClassMethod swap( ByRef x, ByRef y) { s tmp=x,x=y,y=tmp } /// d ##class(dc.a).Test() ClassMethod Test(N = {1e7}) { #define swap(%x,%y) s ##unique(new)=%x,%x=%y,%y=##unique(old) s a=3,b=7 s t=$zh f i=1:1:N s tmp=a,a=b,b=tmp w "inline procedure",?20,$zh-t," sec",! s t=$zh f i=1:1:N d swap w "just a procedure",?20,$zh-t," sec",! s t=$zh f i=1:1:N $$$swap(a,b) w "macros procedure",?20,$zh-t," sec",! s t=$zh f i=1:1:N d ..swap(.a,.b) w "class method",?20,$zh-t," sec",! swap() s tmp=a,a=b,b=tmp } } ;dc.a.1 ;Generated for class dc.a. Do NOT edit. 09.06.2025 00:00:00PM ;;00000000;dc.a ; Test(N) methodimpl { s:'($d(N)#2) N=1e7 s a=3,b=7 s t=$zh f i=1:1:N s tmp=a,a=b,b=tmp w "inline procedure",?20,$zh-t," sec",! s t=$zh f i=1:1:N d swap w "just a procedure",?20,$zh-t," sec",! s t=$zh f i=1:1:N s %mmmu1=a,a=b,b=%mmmu1 w "macros procedure",?20,$zh-t," sec",! s t=$zh f i=1:1:N d ..swap(.a,.b) w "class method",?20,$zh-t," sec",! swap() s tmp=a,a=b,b=tmp } swap(x,y) methodimpl { s tmp=x,x=y,y=tmp } When implementing a sorting algorithm doing lots of swaps, this can increase the execution speed. PS: And yes, avoid passing input/output parameters and class methods due to the high overhead of calling them.
